When you leave the ski area boundaries, you assume all risk. Here in Colorado, we have skiers every now and then that ski out of bounds and end up dead, usually in avalanches. It’s not necessarily against the rules to do so; some ski areas have gates that allow exiting the boundary, but they all have warnings at those gates about the risks.
when I skied Gran Targhee, the staff told us to stay with a buddy. they recovered bodies in the spring... if you went off the trail and hit a tree, the snow fall off the tree would bury you without a trace. that was in the 80’s.. no cell phones then.. and thats what 30-40 feet of snow will get ya!
Well, if that is the case, he like all self centered adventure seekers did not assume the risk of 200 rescuers and air support.
