Alpine Tips
Creek crossing safety
Creek crossing is a common and potentially dangerous part of many mountaineering approaches. Here are some simple techniques to lower the risk.

Crossing a stream or creek is often a part of mountaineering approach hike, and it’s potentially one of the most dangerous parts of the climb. Here are a few tips (gleaned from several whitewater rescue courses I’ve taken) that can make this a bit safer.
Always face upstream.
Wear shoes. Yes, your shoes will get wet, but your footing will be much more secure.
Using poles (trekking poles or sturdy sticks), one in each hand, is the single best way to improve your balance in a crossing. Not enough poles for everyone? Toss them back once one person is across.
Take some time to scout. Look upstream or downstream to check for a friendlier crossing if you don’t like what you see when you first arrive.
Snowmelt streams are usually lower in the morning. Consider an early morning crossing to have lower water levels.
Water depth rule of thumb: if the water is moving fast and over your knees, you should take extra caution. Note that this rule does not apply equally to taller/shorter team members, and the speed of the water has a great affect on the potential hazard of the crossing.
Be extra careful on snow bridges. Punching through the snow and into the creek can be deadly.
Cross in a three person triangle – Moving in unison across the creek as a group can add stability to everyone. Make a triangle, with the “point” being the largest person, who faces upstream. The point person has a pole in each hand. The other two members of the triangle have a pole in the outside hand and one hand on the shoulder or pack of the point person. The larger point person makes an eddy of sorts with their legs, providing an area of slack water for the inside legs of the two back people. If the back people start to slip, they can grab the other members on their triangle and hopefully recover.
Remove your pack waist belt so you can quickly ditch your pack if you fall in. On a really challenging crossing, you may want to completely remove your pack. Have another stronger person carry it, or maybe rig a clothesline loop rope across the creek and ferry the packs across one by one.
Try to find a crossing point that has a friendly runout; if you were to lose your footing and fall in, you’re not going to be swept over a waterfall, or into dangerous rocks or a log jam.
See this this nice article at PCTA.org for a more detailed look at this important skill.
DIY - Replace that gaiter cord with a cable
Lightweight gaiters often have a weak spot - the cord under your foot can easily fray and break. Replace it with a thin cable.
A weak point in the design of some gaiters is the cord that runs under the sole of your boot. While some models have a beefy (and heavy) strap, some have just a nylon cord. After stomping around on rough terrain, the cord gets frayed and cut. As it’s on the bottom of your boot, it’s hard to notice when it’s almost cut through.
Here’s an easy modification that will eliminate this hassle. Head to the hardware store, and buy 3 feet of 1/16 inch cable from the bulk spools and 4 1/16” aluminum sleeves.
With wire cutters and a bit of patience, you replace the cord with the cable. Clamp the aluminum sleeve onto one side of the wire with pliers, or smack it with a hammer. Note that this is non-adjustable, so size it to the shoes you’ll use most often with the gaiters, and measure carefully before that final smushing of the second aluminum sleeve.
Cut the cable, and repeat for your other shoe.
When you're done, it should look like this.
The perfect backcountry storage bottle
Gerber kiddie juice bottles - the perfect storage solution for small amounts of most anything.
Looking for a small plastic bottle for food storage, and want a light weight, super-tough food grade plastic, a bomber non-leaking cap, and don’t want to pay $2-3 for a mini Nalgene?
Check out Gerber baby juice bottles (about $1.99 for a 4 pack as of 2018) in the baby food aisle at the supermarket.
Drink the juice if you like, but the great plastic bottles are the real score. I use them for olives, olive oil, sports drink mix, and espresso brought from home.
The empty 4 oz. bottle weighs just 21 grams.
Estimate time to sundown with your hand
Wondering how long it will be until the sun sets behind that ridge? The answer is at hand. =^)
When it’s late afternoon and you’re wondering if you should make camp or not, use this trick for estimating the time until sundown.
Extend your arm and your fingers toward the sun, then bend your wrist. Each finger represents about 15 minutes. Leapfrog your other hand if needed to estimate times more than 1 hour.
This trick works if the horizon is flat or a mountain ridge line, it doesn't matter. Note this is an approximation, and varies a bit depending on your latitude.
In my neighborhood in the Pacific Northwest, a good rule of thumb to total darkness is add about 30 minutes to the sunset time. So, if your hand (or your smartphone) tells you sunset will be in one hour, you have about one hour 30 minutes of usable light. This will depend on your latitude, test it in your local area to be sure.
The same applies to usable light in the morning; subtract 30 minutes from sunrise time to find the first usable light. For alpine starts, this can help you plan your wake up time, as being on more technical terrain when you can see where you're going is usually a good idea.
Example: from your camp, you have an hour of easy walking on a trail before some technical climbing begins. You and your partners want to have a fairly leisurely hour to get ready after you wake up. Your phone's weather app tells you that sunrise is at 6:15am.
Subtract 30 minutes from 6:15, and you get first usable light at 5:45. Subtract two hours from that, and you get an approximate wake up time of about 3:45 am.
Minimize rock fall - clip some gear in easy terrain
Are you roped up and ascending an easy but loose, chossy gully? Put in a few cams and clip the rope to lift it away from the loose rocks.
Here’s another solid tip from the excellent American Mountain Guide Association (AMGA) video series, featuring IFMGA Certified Guide Emilie Drinkwater of Cloudsplitter Mountain Guides.
Scenario: You and your partner are on 3rd-ish class terrain with a fair amount of loose rock. Ideally, you might take a minute or so and shorten up the rope with a Kiwi coil and walk with just a few meters of rope between you, but for whatever reason you decide not to do this.
A simple way to keep the rope from getting hung up on the rocks, as well as the rope potentially causing rocks to tumble down onto your follower, is to simply find a few high gear placements along the way and clip the rope into them.
The gear placements are not needed for fall protection, they just keep the rope out of the rocks. Probably best to use a cam if possible, to make cleaning fast and easy for your follower.
Check the short video below for a demo.
Speeding up a group rappel
Does your larger climbing team have two rappels ahead to make it to safe ground? Here’s a simple way to speed up the process.
Scenario: You’re descending a route with a team of four, and you have one rope. You get to the rappel spot, which requires two raps on a single rope to get down to safe ground.
Standard practice would be to have everyone rappel on two strands to the next station, and then have everyone rappel again to get to the ground. For your team of four, this means eight total raps . . . and a lot of time.
Consider this alternative:
Fix one end of the rope at the top.
Have the first three people rap to safe ground on a single strand.
The last person (a more skilled team member) unties the fixed rope end, pulls up half the rope and threads the anchor as for a normal two-strand rap. Then, this last person raps to the intermediate station and then finally to the ground. This results in a total of five raps rather than eight, speeding up your team’s descent time.
Be sure everyone on the team is comfortable rapping on a single strand, and add some extra friction to the rap if necessary. See this tip on more ways to add friction to a rappel.
DIY - Rope protector for a fixed rope
Are you setting up any sort of fixed rope where it might get loaded over an edge? Having some sort of protection on that spot for your rope is a Good Idea. Here's a quick way to make a DIY rope protector.
You’re taking a friend on Monkey Face at Smith Rock. The plan is for you to lead the aid pitch, fix the rope, and have your partner ascend the fixed rope and clean the gear in standard aid climbing technique . . . but you remember that from the anchor, the rope goes over a rather sharply angled edge before drops to your partner.
Yes, thousands of people have done this pitch without any damage to the rope, but you'd still feel a little better if your rope was protected. This is a pretty common situation in aid climbing, making a fixed rope anchor, or caving. Anytime you have a loaded rope over a rock edge, padding the edge or protecting the rope in some way should be considered. (Even more so if the rock has sharp crystals, like Joshua Tree granite.)
You can do this on the fly by putting a backpack under the rope to protect it. But if you know you're going to have this situation, it's more secure to have a designated rope guard that you bring with you.
Yes, you can buy a commercial one like these for about $20. If you’re in an instructional environment and find yourself doing this often, this is the way to go.

But, it’s easy and cheaper to DIY. You can use either heater hose from the car part store, which is convenient because you can buy it by the foot, or a section of cut up retired garden hose, if you have access to that. You need about 18 inches / 45 cm of hose.
Steps:
Go to the car parts store, and buy a couple of feet of 1/2 inch heater hose. It shouldn’t cost more than about $1.50 per foot. (Some hoses used in cars are reinforced and cost more like for $5 a foot, don't buy this type.) The 1/2 inch hose works pretty well with about a 10 mm rope. You probably don't want to be using a fixed line that's much smaller than that anyway. You may want to actually bring your rope into the car parts store, and buy a hose with a diameter just slightly bigger than the rope you think you're going to use.
Carefully cut a slit the length of the hose with a utility knife or something similar.
Drill out a small hole an inch or so away from one end, and put in a keeper cord of shoelace, 2 mm cord, or some similar material. Remember, everything you take with you climbing needs to have a way to get clipped in.
To use, open the slit in the hose, insert your rope, and slide the hose so the middle of it is over the loaded edge. If you want to be extra cautious, you can wrap athletic tape around the hose, as well as a bit on the rope to secure it in place, Alternatively, you can put a prusik knot on the rope above the hose, and clip the prusik to the keeper cord to hold everything in the right spot.

To really make it secure, you can wrap the whole thing with athletic tape.
Securing yourself near a cliff top
Setting up a top rope anchor from above can place you dangerously close to the cliff edge. Here’s a simple and fast way to safeguard yourself whenever you’re working close to a drop off.
When setting up a toprope or rappel anchor on a clifftop, a good rule of thumb: secure yourself if you’re within 2 meters of the edge.
This distance may be greater if the terrain slopes toward the void, there’s loose gravel/stones underfoot, the rock is wet, or other factors.
A fatal accident happened at Horsethief Butte Washington in 2009, apparently because climbers were setting top rope anchors in an exposed area without an adequate backup.
Let’s learn from this tragedy and never let it happen again.
There are various ways to secure yourself. One method that uses a minimum of gear is to use your climbing rope.
First, locate or build a secure anchor well back from the cliff edge. This anchor can be a stout boulder or rock spike, tree, or a constructed gear anchor.
Tie one end of your climbing rope to this anchor.
Tie a friction hitch (prusik, klemheist, or autoblock) to the fixed line, and clip the friction hitch to your belay loop with a locking carabiner. (You can use a Grigri for this, but they can slide under a mild load, so I prefer a friction hitch.)
Walk to about 2 meters from the cliff edge, sliding the friction hitch along the rope as you walk. Then, pull up about 3 meters of slack rope, tie a figure eight or overhand on a bight, and clip this with a locking carabiner to your belay loop. The friction knot allows you to walk out to an exposed area under a self belay. The bight knot backup is there in case the friction hitch fails in any way. With this simple rig, you can work at the edge of a cliff fully protected from falling.
If you’re building a toprope anchor, after the anchor is built, simply pass the free end of your fixed safety line through the master point carabiner, and drop it to the ground. Then walk away from the cliff edge (still attached to your safety line) to a secure area, untie the end of the fixed rope, and toss it to the ground. The rope should be through your anchor and both ends should be on the ground, ready to climb.
What about a Grigri?
A Grigri can work, but it can start to creep along the rope if you don't keep constant weight on it. If you have to actually rappel to go over an edge to access the anchors, it can be a good choice. If I'm staying more or less at the top, I prefer a friction hitch, as it’s more reliable. Try both and see what you prefer.
Here's a short video I made showing this method, and why a Grigri sometimes doesn't work so well.
Here's a nice Instagram video from IFMGA Certified Guide Karsten Delap showing the whole process, using the actual climbing rope and a Grigri to access anchors below the edge.
A report of the Horsethief Butte accident is below.
From The Columbian newspaper:
Deaths of rock climbers in Gorge blamed on error
Tuesday, May 26 2009
BY JOHN BRANTON
COLUMBIAN STAFF WRITER
A state investigation of a rock-climbing accident that claimed the life of a Washougal man and his sister-in-law has determined they fell due to errors in placing metal stoppers in cracks and attaching them to their webbing.
The early afternoon fall on April 5 killed Tony “T.C.” Silva of Washougal and Laura Dyal-Silva of Oregon during a family outing at Horsethief Butte, in Columbia Hills State Park in Klickitat County.
Tony Silva was a popular and well-respected detective with the Gresham, Ore., Police Department who was known for his advanced computer skills and helping other officers.
An investigation revealed that the deaths were accidental and not caused by equipment failure, Lt. Julie Myer of the Washington State Patrol, based in Olympia, said Tuesday.
For such a climb, three wedgelike metal stoppers, wider on top and narrower on bottom, typically would be placed in cracks, Myer said. The climbers would fasten their webbing to cables on the stoppers.
Myer said Dyal-Silva had more training than Tony Silva, who was attempting to lodge the three stoppers.
Tony Silva had successfully placed one stopper and attached it to the climbers’ webbing.
The second stopper had been placed in another crack, but wasn’t attached to the webbing.
The fact that the webbing was all one color, gray, may have caused some confusion about whether the second stopper was attached to it, Myer said.
Tony Silva is believed to have been working on placing the third stopper when something happened, perhaps a slip. At least one witness said Tony Silva fell first, then Dyal-Silva, who was attached to the system with him.
Their webbing was attached to only one stopper, Myer said.
“We know he was connected to one stopper that failed when all their weight got onto it,” Myer said.
They fell about 42 feet.
Dyal-Silva’s husband, Bobby Silva, had been on top of the cliff but went down to get the families’ children out of the sun, Myer said.
Rock climbing takes a lot of training said Myer, herself a climber.
“You have to constantly practice to retain that skill level.”
Two ways to melt snow with solar power
No, you don’t always need that $220(!) MSR Reactor stove to melt snow at your high camp. Try free solar power instead.
Melting snow for water is a time and fuel consuming part of winter camping and many overnight snow climbs. If you have a base camp and the sun is out, try passive solar power to get some extra water. You do need a large black garbage bag for this to work, which is something you probably want to have in your pack anyway, because it serves lots of other purposes, like a pack cover, glissade device, and emergency shelter.
Here's two methods to melt snow via solar power.
First, the simplest method, if you have some exposed rocks nearby. Put some snow in a black garbage bag, secure the top, and put the bag on the (somewhat) warm rock. This should melt the snow in an hour or two.
Second, slightly more complicated, works on snow when you don't have any exposed rock.
Find a slight downward slope on snow.
Make a slight concave surface in the snow, slightly larger than your garbage bag.
Lay a sleeping pad on the snow, and put the garbage bag on top of it.
Pack some snow around the edges of the pad and bag so it doesn't blow away.
Put a small amount snow on the surface of the bag in a shallow layer, and add a picket to make a “V” for the meltwater.
Put a cook pot at the bottom underneath to catch the drips. Monitor, and add more snow as needed.

A good system for cleaning and racking gear
Having a standard system to rack gear when you’re cleaning as a second will greatly speed up your climbing efficiency. Here’s a simple way to do this.
Rather than clipping gear randomly onto your harness when cleaning, have a dedicated system and stick with it. This one works great.
Before the second leaves the belay, they drape two single runners over their shoulders, one on each side. When they clean, all of the protection (cams, stoppers, etc) gets clipped to one side, say the right, and all the quickdraws, runners and extra carabiners get clipped to the left. Then at the next belay, the second can easily lift these slings off of their head and quickly rerack the gear.
If they keep this pretty organized when they are cleaning, at the belay all they have to do is grab any remaining gear from the leader, and then the second is ready to head out on the next pitch.
Here’s a short video clip by big wall expert and Supertopo founder Chris McNamara taking about this cleaning technique (starts at 1:25).

I recently came across this clever online tool from alpinerecreation.com, a New Zealand based guiding company.
It’s a mechanical advantage calculator, very cool!
This is an excellent way to instantly see some of the forces involved with different rigging methods, and how using a carabiner rather than a pulley can change the efficiency of your system.
(Works fine on a mobile phone but it's easier to see the big picture on a wider computer screen.)
Choose your hauling system (2:1. 3:1, 5:1, 6:1, etc.)
Choose your components (Micro Traxion, rescue pulley, large carabiner, small carabiner, etc.)
Choose your load (default is 100 kg)
Choose your units (percentage of load, kg, or kN)
Press “Calculate” and it gives you values and forces all the way through the system!
Here’s a screen grab showing values for a 3:1 Z drag, using a Micro Traxion as the progress capture and a good quality pulley on the “tractor”.

DIY - Protect shoe threads with super glue
Are you battering your light hikers with rough terrain? Super glue on the shoe threads will help.
You can increase the amount of mileage you can get out of trail runners and lightweight boots by coating all the threads on the seams with super glue.
It protects the threads and stops any fraying from spreading if it does start.

Gaia GPS tip- long touch to measure distance between map points
In Gaia GPS, the “create route” tool is a sort of hack to quickly see the distance between two or more points on your map.
Gaia GPS is the favorite GPS navigation app here at AlpineSavvy. Here’s a Gaia tip to quickly measure distance between two or more points on a map.
In Gaia GPS, if you long touch the map screen, that starts the “create route” function.
This is a handy way to get a quick direct line distance between two or more points.
Zoom in to your area of interest. Long touch your first point. A blue dot should appear on your screen, and a small box showing the distance and bearing from your current position.
Look in the lower left corner of your screen. You should see a bird icon which indicates “as the bird flies”, or straight-line distance.
If you want the actual driving or hiking mileage between points, tap the “mode” icon and change it to hiking or driving.
Do another long touch on point B.
A red line should draw between the two points, and the line should be labeled with the distance in miles.
Continue long touching any additional points as needed. The length of each leg will show on each red line, and the cumulative distance is on a graph at the bottom of the screen.
Make a note of the distance, then tap cancel at the top to delete that route.
Examples: Straight line distance between 2 cities:
Rough mileage around Green Lake Park in Seattle. You can see the links of each short leg on the red lines, and the total length at the bottom.
Two good reasons to mark the middle of your rope
There's two good reasons to mark the middle of your rope. One is hopefully pretty obvious, the other one not so much, but perhaps more important.
There's two smart reasons to mark the middle of your rope. The first one might be rather obvious, the second one perhaps less so, but it may be more important. Let's have a look at both.
1 - Setting up a rappel
Knowing with certainty that the middle of your rope is at the rap anchor is a Good Thing. Of course, if you cut off the end of your rope for any reason, this middle mark becomes less accurate. But that is pretty darn rare, so a permanent mark on your rope should last you for a long time.
Yes, you can do the trick of measuring hand spans to find the middle of your rope, which actually is pretty darn accurate, but having a middle mark makes it idiot-proof.
2 - Belay Safety
This is one people may not think about right away, but it’s arguably more important. For decades, pretty much everyone climbed with a 50 meter rope, and you would never find a single pitch sport climbing anchor more than 25 meters off the ground. But many newer routes are longer, requiring a 60, 70 or even 80 meter rope. Because these long routes are generally newer, they may not appear in a guidebook, and there's often not a reliable way to tell at the base of the route precisely how long it is.
If you’re belaying the leader, and you notice the middle mark of the rope pass through your belay device before the leader has reached the anchor, that should ring a LOUD alarm bell in your head! You're not going to have enough rope to lower them off and reach the ground, and you need to figure out a crafty solution to a potentially serious problem.
A quick review of the report/book “Accidents in North American Climbing”, published annually by the American Alpine club, can confirm that this is a recurring problem. One likely cause is the increase in the number of routes that require a 70 meter rope, as mentioned previously.
Another contributing factor is probably more gym climbers venturing outside. In a gym, routes are almost always less than 30 meters tall, and therefore the 60 meter rope that many gym climbers have for leading is guaranteed to be long enough.
While many people climbing single pitch routes from the ground don’t bother tying into the end of the rope or even having a stopper knot, doing either of these simple fixes eliminates the problem of potentially dropping your leader when you’re lowering them off.
(Even if you have a 70 meter rope for a route designed for it, if those anchors are close to 35 meters off the ground, and the belayer decide to back up a little bit, that could still cause you to end up short when you’re lowering. So, just having a 70 meter rope doesn’t necessarily eliminate the problem.)
So, how best to mark the middle of your rope?
There's been a L O N G debate on the interwebs about the safety of using things like Sharpie pens and laundry markers to mark the middle. We’re not going to rehash those here.
An excellent choice is to go with a designated rope marker made by the French company Beal, one of the largest rope manufacturers in the world. It’s inexpensive and has a specially formulated ink in a handy dispenser that's designed for climbing ropes. Get one, use it, and share the extra ink with your friends.
Beal rope marker
If you want to make a quick temporary mark, find the middle of your rope and then put some tape on it if you have some. This is a short term solution, because it doesn't pass through a belay device very well and can fall off.
Summary:
If you’re leading a lot of sport routes outside, you probably want a 70 meter rope, which is pretty much the new standard.
Put a middle mark on your rope if it doesn’t have one. Use it to set up rappels and also for belay safety.
Use the generally accepted best practice of a closed rope system. For toproping, this means the belayer is either tied into the end of the rope, has a solid stopper knot tied into the end, or has the end tied to something reasonably heavy like a backpack. to avoid any chance of dropping the leader when lowering.
Think you’d never make a mistake like this? Well, if it can happen to Alex Honnold, it can damn sure happen to you.
In 2016, Alex was dropped by his belayer because they were using a 60 meter rope on a 70 meter route, there was no knot in the end of the rope, and his belayer was not tied to the end of the rope. While she was lowering Alex, the end of the rope zinged through her Grigri and Alex fell onto some “gnarly rocks”.
Would a middle mark have prevented this accident? Hard to say. But it would not have hurt anything.
Read the complete accident account here, from “Accidents in North American Climbing”, an annual publication of the American Alpine Club.
Below is a copy paste.
I had run up the route Godzilla (5.9) to put up a top-rope for my girlfriend and her family. At the last second her parents asked us to hang their rope instead of ours. I didn't think about it, but their rope was a 60m and mine was a 70m. I was climbing in approach shoes and everyone was chatting at the base—super casual, very relaxed. As I was lowering, we ran out of rope a few meters above the ground and my belayer accidentally let the end of the rope run through her brake hand and belay device.
I dropped a few meters onto pretty gnarly rocks, landing on my butt and side and injuring my back a bit (compression fracture of two vertebrae).
Analysis
Lots of things should have been done better—we should have thought about how long the rope was, we should have been paying more attention, we should have had a knot in the end of the rope. I wasn't wearing a helmet and was lucky to not injure my head—had I landed on my head, it probably would have been disastrous. My belayer had been climbing less than a year. Basically, things were all just a bit too lax. (Source: Alex Honnold.)
A Better Way to use your compass lanyard
Most people think the string/lanyard on your compass is for hanging around your neck. That’s actually not the best place.
Most good quality compasses, such as our favorite, the Suunto M3, come with a lanyard cord. Many people assume this is for hanging the compass around your neck.
You could do this, but unless you’re about 3 feet tall, you’ll find that in order to properly use the compass to take a bearing by holding it at your waist, the cord isn’t long enough. So, if you hang the compass around your neck, every time you want to use it, you have to take it off, which is kind of a bother if you’re using your compass a lot.
Here’s a better approach. If you are using your compass a bunch, girth hitch the lanyard cord through a belt loop, near the front pocket of your pants or shorts, then just put the compass in your pocket.
There’s two main advantages to doing this. One you can easily hold the compass at waist level to take a bearing, and two, you can never lose your compass because it’s permanently tied onto your pants.
Now, let’s be realistic, 99% of the time you are not going to be traveling in the backcountry with your compass glued to your hand like this. But for those times when you do have to use it, this is a great way to carry it.
Survival shelter for an unexpected night out
Looking for a lightweight, inexpensive and versatile emergency backcountry shelter? Using this common item is a great choice.
In the book “Analysis of Lost Person Behavior” author William Syrotuck analyzed over 200 rescue cases. He found that 11% ended in fatalities, and three quarters of those people who died generally did so from hypothermia, within the first 48 hours of becoming lost.
So, to look at these statistics in a more positive way:
If you’re lost, you have an approximately 90% chance of surviving.
If you can stay alive for 2 days and minimize the chances of getting hypothermia, your survival odds increase to around 97%.
This tells us that carrying some kind of emergency shelter is an excellent idea.
But what, exactly does that mean? A one person tent, a tarp, a bivy sack, maybe even a bothy bag, which is kind of a British combination of all three? Or something more minimal?
If you have a reasonable chance of spending a night out, you probably want something fairly substantial, like a bivy sack and tarp. But, if you're after something to keep in your hiking day pack for emergency use only, something lighter which takes up less space is probably a better choice.
For emergency use, go with simple: a heavy duty garbage bag. Cost: about $1, weight, about 5 ounces / 140 grams.
As a survival shelter, cut a small slit in the side end for your head, see the video below. If you're about average height, you can probably crouch over and get most of your whole body inside the bag. If you're tall than that, you might want to bring two bags, one for your feet and one for your torso and head.
Also, the bag serves as a rain cover for your pack, and easily converted into a poncho if you cut a hole for your neck and arms.
Be sure and get the heavy duty “contractor clean-up bags”, that are huge (typically 43 gallons) and 3 mil thick. (Side note: a “mil” means one 1000th of an inch, and is a standard in the United States for measuring the thickness of plastic. It’s not a millimeter or a milliliter.)
At the big box hardware stores, you usually need to buy a humongo box of 50 of these, so if you know anyone who’s a builder you could ask them for a couple of extras. Or, they’re available on Amazon as a more reasonably sized box of 20.
After some hunting around, I was able to find some that are orange, better for increased visibility, unfortunately available in a pack of 50. So I've been sharing them with various climbing friends and students over the years. Try a Google for “orange 3 mil 42 gallon contractor trash bags". I found mine from plasticplace.com.
Many backpacks have a water bladder pocket, or maybe a pocket to hold a foam pad as part of the suspension. You can slip the bag in this pocket; you're not notice the weight and it’ll always be in your backpack.
These are the bags I got from Amazon:
Here is a nice short video from the excellent MedWild YouTube channel on making a quick emergency shelter with a garbage bag. Note that he cuts just a small hole in the SIDE of the bag, which lets you breathe and see, but keeps your head protected.
Many people want to cut a hole for your head in the top of the bag, which keeps your head exposed. The hole in the side is much better. Here's a screen grab from the video showing this simple technique.

And here's the whole video:
What about mylar “space” blankets or mylar bivy sacks?
Lots of people carry these for emergency use. But they have a few issues:
Yes, they can reflect some of your body heat back, but if you're getting hypothermic, there's not much heat being generated in the first place. If you have proper clothing on, that should be doing its job of keeping heat close to your body.
If you have the mylar against your bare skin, the blanket will conduct the heat away from you into the cold air. The same thing happens if you put it on bare ground, heat conductivity from your butt into the earth.
The very inexpensive ones are extremely fragile and start ripping if you sneeze on them, so don't even bother buying those.
Most emergency bivy sacks are pretty much non-breathable, so you can expect to get a fair amount of condensation and wetness inside your bag. The advantage to the garbage bag is that you can get a bit of airflow from your feet up through your head, which minimizes condensation.
Given the choice between a garbage bag and a mylar space blanket, take the garbage bag.
The mylar blankets and bags may not be very good when used by themselves, but they do have some other wilderness survival applications. If you do choose to take one, spend just a few extra bucks and get one of good quality that's much sturdier. SOL makes some nice ones, called Heat Sheets. They cost just about $10 for a 2 pack.
CalTopo tip - Try the "MapBuilder Topo" layer
Caltopo has one map base layer that’s a superb choice for most any backcountry adventure - MapBuilder Topo. See a side-by-side comparison of the old-school USGS map.
If you're new to using CalTopo mapping software, watch this tutorial to get started.
CalTopo, in my opinion the best online and free mapping software, continually rolls out great new features. There’s a (relatively) new map layer, called "MapBuilder Topo” that is a terrific option for printing outdoor recreation maps. It's a big improvement over the standard USGS 7.5 minute map layer.
What’s cool about it?
Shaded relief (shows terrain features like ridges and gullies more clearly)
Easy to see and well-labeled contour intervals
Roads and trails easily visible and labeled
Some distracting non-essential map information (such as unnecessary text, public lands survey section lines and wilderness boundaries) removed or made less prominent
County lines added in yellow (it’s helpful to know what county you‘re in if a rescue is needed)
Shows approximate vegetation and terrain boundaries, such as forest, rock, and snow/glacier, even crevasses
Have a look yourself!
Go to caltopo.com
Mouseover the “Base Layer” icon in the top right corner
Select "MapBuilder Topo” from the drop down menu (should be the first choice at the top)
Zoom in to your area of interest. Swap back and forth between this map layer and USGS to see the differences. (Note that the map tiles may take longer to generate on your computer and also to print when using this layer.)
Here’s an example of Mt. Hood south side in the standard, old-school US Geological Survey 7.5 minute topo map.
Note that there’s no relief shading, trails are hard to spot, there’s unnecessary “Mount Hood” text in a large font, the chairlift isn’t shown. Not bad, but definitely room for improvement.
Now, here’s the same map area in the MapBuilder Topo layer. Improvements:
the relief shading makes the gullies and ridges much more obvious
county line (yellow) is labeled
ski chairlift is shown (very handy for finding your way back down in low visibility)
trails are clearly delineated and labeled
every index contour has an elevation label
green wilderness area boundary is current and correct
Which map would you rather use? The USGS 7 1/2 minute maps for many decades were the only game in town, and unfortunately that’s what some old-school navigation classes and textbooks still advise you to use. But, for most people and most activities, these are no longer the best choice.
Get with the modern times, learn to use mapping tools like CalTopo, and you can have a superior map for free!
And, if you think CalTopo is great, I strongly encourage you to support CalTopo with a $20 annual subscription. There is just one guy running this entire software platform, and your modest annual subscription can help ensure that this great service continues on into the future.
Having a subscription also gives you some nice perks, like being able to print on larger size paper, and being able to save and share your maps to the cloud. When you consider that a single commercial map of just one area can cost between $10 and $15 at the outdoor store, a $20 annual subscription to this mapping software is a pretty screaming deal.

Add custom map layers to GaiaGPS
Gaia GPS is a great navigation app for your smartphone, with loads of map layers to choose from. Even so, you may want to access ones they don't have, such as Google Earth satellite imagery or Open Topo. Adding a custom map layer is easy once you know how.
Gaia GPS is regarded as one of the best backcountry GPS apps for your smartphone. They offer a wide variety of base maps to choose from, but one of my personal favorites, called Open Topo, happens to not be one of them.
What makes Open Topo a terrific choice for outdoor adventures? It has nice shaded relief (which makes features like ridges and gullies much easier to see), updated trails and roads, and land cover, such as forest, rock, or snow. (One potential curveball for Americanos - elevations and contours are in meters.)
Go have a look yourself. Go to opentopomap.org and zoom into your favorite part of the world.
Here’s a screengrab of Mount Rainier in Open Topo. Pretty cool, eh? Like I said, elevations are in meters.
The one small downside is that it is not part of the Gaia GPS app.
The good news is, with a little computer sorcery, you can add this as a custom map layer to your Gaia GPS phone app. Here's how to do it.
These steps might sound a little complicated, but it's pretty straightforward. Keep this webpage open in a browser tab so you have a reference.
Here's a nice video that shows how to do it, using Google Earth.
Here are the step-by-step instructions, for a different map source as mentioned above, Open Topo.
1. On a desktop computer (not your phone), go to GaiaGPS.com. Log in to your account, or create an account if you don’t have one.
2. Click your user name (top right of screen), and from the drop down box select "Map Sources".
3. Click "Import an External Map Source".
4. In the “Name the Map” box, give it a name. I suggest a simple, descriptive, name, like “Open Topo custom“.
5. Scroll a bit lower, locate "Paste your modified link here"
6. Copy and paste this link in that box:
https://c.tile.opentopomap.org/{z}/{x}/{y}.png
7. Scroll to the bottom, click "Add this Map Source"
Go to your phone.
8. Make sure you are signed in to your Gaia account on your phone. [Settings icon > Account > Login) and that “Sync/Backup” is toggled on.
9. Restart the app.
10. Tap the Map Sources icon, top right of your screen. Tap Edit, then scroll to the bottom and tap “Custom Imports”.
11. You should see “Open Topo Custom” here, or whatever you decided to name it. Select this map layer to add it to your viewable layers. You should now be able to use Open Topo on your phone.

See the Exact Right Spot with lat/long coordinates on Google
Google maps and driving directions works great in the city, where places have street addresses. But what do you do in the backcountry? Answer: use latitude longitude coordinates in decimal degrees, to pinpoint any spot in the world and (usually) get driving directions to it.
Most of us have suffered through trying to follow well-meaning but wildly confusing directions to get to a remote trailhead or campsite on obscure fire / logging roads.
The directions usually look something like: “Turn off the main road, then go to .7 miles on Forest Road 1234. At the 3-way fork, take the middle fork on road 1234-10, then go 3.2 miles on that, and then . . . ” You get the idea. And if any new roads have been added or removed since the guidebook got printed, or some local yahoos have been shooting up the road signs so you can’t read them, then things REALLY get confusing!
Here’s a superior system for giving a precise location, and ideally directions, to most anywhere that doesn’t have an actual street address. Which is most of the fun places we want to go play, right?
If you type latitude longitude coordinates (preferably in decimal degree format) into a Google search or a smartphone mapping app, it places a marker directly on the spot. You can then get driving directions to it.
Try it! Here’s the lat long coordinates in decimal degree format for the Mt. Thielsen trailhead in southern Oregon:
43.1459, -122.1277
(If there are any guide book authors reading this, can you please please please start using latitude longitude decimal degree corners to describe Important Places in your book?)
Note:
- Use a comma between the latitude and the longitude.
- Be sure to include the “minus” sign before the longitude. This indicating west longitude rather than east. If your intended map of the Pacific NW instead draws in China, then you probably skipped the minus sign. =^)
Note the number of decimal places. In this example, we are using four. If you use less than four decimal places, Google doesn’t recognize it as a coordinate and thinks it’s some kind of a math problem.
Four decimal places gives you positional accuracy down to about 3 meters. We’re not measuring property boundaries here, so for things like finding your tent in the woods or locating a trailhead, four decimal places is fine. If you use a GPS app on your phone, you may see a coordinate of six or even seven decimal places. This is theoretically accurate down to sub 1 meter, but that’s a little deceiving because the GPS chip on your phone is not that good. When I get a six digit coordinate from my phone or mapping app, I usually just remove the last two digits until I get down to four decimal places. That is simpler and easier to transmit and write down.
You can get decimal degree coordinates in several ways.
Probably the easiest is to go to Google maps and zoom in on your area of interest. Right-click, and choose “What’s here?” This opens a pop up box. The latitude longitude coordinates in decimal degrees, of the exact point you clicked, appear at the bottom of the box. Copy and paste the coordinates into a new Google search to test. If it draws your spot correctly, your coordinates are correct.
Go to caltopo.com, the best online mapping software. Using the different map layers from the upper right corner, choose one that lets you zoom in to your area of interest. The coordinates of the cursor are shown in the upper right corner. Change the coordinate type to “Degrees” from the “Config” menu at the top of the page. Also, you can right click and choose “New > Marker”, and you should get a pop-up box with the location of the coordinates, which you can then copy and paste.
Note:
- UTM coordinates, the preferred coordinate system for backcountry navigation with map and compass, are NOT recognized by a Google search.
- Latitude longitude coordinates in the traditional degrees minutes and seconds and the more specialized format called degree minutes ARE recognized with a Google search, but these are harder to obtain and it’s easy to screw them up when you enter the coordinates. (The “degree minutes” system is typically used by electronic navigation systems in ships and airplanes, and usually not much by civilians.) So, it’s usually best to stick with decimal degrees as shown above.
Other examples of coordinate systems, all showing the same location, the Mt Thielsen trailhead:
UTM: 10T 570913E 4777387N
Latitude longitude, degrees minutes and seconds: 43°08’46”, -122°07’41”
Latitude longitude, degree minutes: 43°08.76’, -122°07.68’
Suunto compasses - 3 options for wilderness navigation
There are lots of options for compasses. Let’s make it easy - here’s 3 recommended models from Suunto that should cover the needs of every backcountry traveller.
Suunto, a Finnish company with a great track record of quality compasses, makes a variety of models. Here's an overview of three that should suit the needs of most outdoor travelers.
Generally speaking, it's best to choose a compass that has adjustable declination, which I think is the most important feature. Having adjustable declination let you measure bearings to true north, and thus eliminates any confusing backcountry arithmetic such as adding or subtracting declination.
Having said that, I realize that a compass a piece of gear that some people will rarely use and want to save a few bucks on. So. I'm going to suggest three different price points, think of it as good, better, best, so you can choose the one that looks best for you.
(Note that Alpinesavvy does not have any affiliate marketing links, so I make nothing from the Amazon links below. I include them more as a convenience for you.)
Before we get to the recommended compasses, here are two that I do not recommend. Students often show up with these in me navigation classes, but if you're shopping for your first one, please give these a pass.
The Brunton compass on the left is part of the “TruArc” series. They are unfortunately carried by REI, so a lot of people (unfortunately) buy them there. The problem with these is that the declination adjustment is very difficult to do. They have lots of lousy reviews, and I feel you would do better to buy a Suunto, as recommended below.
The rather strange looking green one on the right is a military style “lensatic” compass. It can be very accurate once you know how to use it, and it's probably good for calling in artillery strikes, But it lacks a lot of the features that civilian users need, so for most people it's not recommended.
Good - Suunto A-10 compass
This is a bare-bones compass, but still a quality instrument. It has what is called “fixed declination”, not adjustable declination. But, everything else about it is solid, including the nice curved base plate which ergonomically fits in your hand, always reminding you of the proper way to hold the compass.
Here’s a trick to deal deal with magnetic declination on this compass (or any other similar baseplate compass this does not have adjustable declination). Carefully draw a line with a medium black sharpie pen from the center of the compass to your local declination on the outer dial. Now, when you want to take a bearing or measure a bearing, you line up the red magnetic needle on this pen mark, and not the red orienteering arrow. Of course, this only works if you stay in your local area. If you travel far away where the declination might be different, you may have to erase this pen mark with a little rubbing alcohol or nail polish remover or some other solvent, and draw again. But, it's one option for the frugal climber.

Suunto A-10 compass
Better - Suunto M3 compass
The Suunto M3 is my personal favorite, which hits the sweet spot between having all the features you need, and none of the ones you don’t.
Here’s what I like about it:
adjustable declination
long baseplate (for taking accurate measurements from a map and drawing bearings on a map, a long baseplate is helpful)
ergonomic design (the curved part fits your hand, eliminating the common mistake of having the “direction of travel” arrow pointing at you rather than your objective)
low cost (about $15 less expensive than a comparable compass with a sighting mirror)
simple and sturdy (fewer moving parts and hinges mean fewer things that can go wrong in the field)
lightweight (no sighting mirror means less weight)
A few words on sighting mirrors . . .
But what about compasses with a sighting mirror, you may wonder. Don’t offer greater precision when taking a bearing? The short answer: Yes, they do, but for almost all backcountry uses of a compass, you don’t need this level of precision. If you’re doing field mapping or walking a straight line when on a search and rescue team, then the slight increased precision of a mirrored compass might be justified. But for the vast majority of the simpler backcountry uses of a compass, like taking a bearing to an object and then either following it or plotting the bearing on a map, the +/- 2 degrees of accuracy you can get with baseplate compass works just fine.
Also, consider that a mirror compass LACKS most of the good qualities listed above.
Most mirrored compasses:
are not ergonomically designed
are expensive
are heavy
have more moving parts that can break
I have used my Suunto M3 compass to take a bearing from a map, follow that bearing cross country for more than a mile, and hit my precise objective . . . at night. With a little practice, you can too. Don’t throw away your mirror compass if you already have one and like it, but if you are looking for a compass to buy, the Suunto M3 or similar model is a better choice for most users.
Cost: about $30 (Oct 2018)
Suunto M3 compass
Best - Suunto MC-2
I know that some people will want a compass with a sighting mirror and possibly a clinometer. Both of these features are found on the Suunto MC-2, which is the next model up from the M3 in terms of the whistles and bells. This costs about $40-$45. Again, I feel this model is not necessary for the majority of users, but if you want these extra features, this compass is a great choice.
Cost: about $45 (Oct 2018)
