Unfortunate, but at that level of recreational risk, such eventual results are at least somewhat to be expected.
Went on a back country ice climb in Feb. in SW Colorado. Show up early, the owner of guide service was there to give me a refresher on avalanches.
He handed me a shovel, avalanche beacon and harness, and an inreach.
My guide was equipped the same.
He got to part about if my guide is buried and how to use the beacon to find him.
I ask what if we are both buried. He calmly said. “ Well then. This is what they use to find both your bodies.”
Love climbing in the winter in San Juan Mountains.
