We need to know avalanches inside and out

An avalanche last month killed an expert skier who was also an avalanche forecaster in Oregon, though his companion survived. What went wrong? Writer Molly Absolon argues that we need to thoroughly investigate how that and other accidents happened, and why— even if some people say that's blaming the victim. The more we learn, she says, the more skiers can make smart decisions about the danger of avalanche.
