Crevasse Rescue Training: The 3:1 Haul
February 13, 2013
This is me talking through a basic 3:1 hauling system for crevasse rescue (didn't know I was being taped!). It assumes a solid anchor has been built and that the victim has been checked on and the lip of the crevasse padded. The anchor is an upright picket equalized with a deadman picket and we also used a deadmen axe as a final backup. I use a prussik-minding pulley on the masterpoint as a ratchet and a tibloc and smaller pulley as a traction device further down the rope.
Less than ideal conditions on St. Mary's Glacier.

I am not an expert!!! Climbing can kill you, use at your own risk.
