Glacier Techniques Workshop, Paradise Glacier, August 13, 2006

A gaggle of ski tourists on the way up from Paradise
The idea of a summer "workshop" to
investigate crevasse rescue techniques not covered in the regular
Glacier Travel and Crevasse Rescue class had been tossed around for
several years, and finally became a reality in August of 2006 as class
leader Darryl Olson put together a Tuesday night seminar at the
Mountaineers Building and a Sunday field trip at Paradise.
Primary topics for discussion included
two-person rope team rescue, leverage systems with short "randonnée
ropes," and rappelling into a crevasse to aid an injured party member.
We assembled for the on-snow workshop at
8:00 AM, with class members scrambling for parking spots in the Paradise
construction zone. As always, a large group of people with skis on their
packs in August was a big hit with the tourists. A little past Pebble
Creek patches of snow started to appear, and some in the group switched
to skis and skins (though I was less optimistic and stuck to trail
runners); we departed the climber's trail to Muir shortly thereafter and
veered southeast toward the Paradise Glacier.
Darryl had scouted the area the previous
weekend, and knew a crevasse he thought would work for our purposes, so
we skied down a hundred feet or so (August turns) and began setting up.
While the rest of the group took a
freeskiing break, Darryl, Maureen and I worked through a couple of
two-person scenarios beginning with just a pack in the crevasse and then
using progressively heavier (Maureen, Darryl) weights. Getting the
initial anchor (ice axe) planted securely proved to be a pivotal moment, and a couple of steps in the rescue process were altered
on the spot. The verdict on two-person rescue? Possible and even probable, but highly dependent upon factors like snow condition,
having your ice axe out or very readily available, relative weight of the victim, and snow friction.
Rappelling into the crevasse to aid an injured victim was put into
practice by a number of the teams, as well as by Darryl who courageously
went down after Jerry White's camera bag/memory card/spare batteries and
managed to snag it with a probe/hook combination.
The simple technique of moving the "C" loop anchor point further down
the rope by tying another figure 8 proved to be a workable way of using
a Canadian Drop Loop system with the new 35 meter ropes, and will be
incorporated into the class next year. Hats off to Darryl for organizing
this event and taking the initiative to buy the new, lighter 9mm ropes -
should make the hike up to the Nisqually much more pleasant for next
year's students!
