Crevasse rescue - remove snow under your pulley
When rigging for crevasse rescue with a progress capture pulley (like the handy Petzl Micro Traxion) on the anchor, sometimes snow or ice can jam into the camming mechanism on the pulley, preventing it from fully grabbing the rope.
There's a simple solution. Dig out a concave “bowl” under the pulley, so it's hanging in space, rather than in direct contact with the snow.
