PRELIMINARY: A snowmobiler was caught in an avalanche in Cabin Creek on the west side of Sage Peak in the southern Madison Range. Six riders assessed that slopes were dangerous and opted not to highmark, deciding instead to ride the lower flanks. One rider triggered the slope from below and was caught and buried 3’ deep under his sled. The ski to his sled was sticking out of the snow and his location was confirmed by a beacon search. He was dug up in 12-15 minutes but did not survive.
