This small soft slab is a good example of the main avalanache problem we're dealing with. Wind loaded slopes below ridgelines are likley areas to find this type of problem. Photo GNFAC

This is the main avalanche problem: avalanches involving wind slabs and new snow. This slide is not too big, maybe 1 foot deep, and did not propagate very wide. Carefully choose slopes based on their ronout zones. Superimpose this slide over other places. It could easily bury a person if it runs into a gully or cause trauma if it pushes you over rocks.

Cornices present a few different problems. First - They can break back farther than you might expect. This problem needs to be considered when traveling along ridgelines. Second - slopes below cornices are often heavily wind loaded. Staying off of slopes below cornices is always a good idea. Photo GNFAC
