Avalanche Details

Triggered a very small wind slab at treeline on Tincan. We searched on wind exposed areas above treeline and were not able to find any other pockets of wind slab. At higher elevations I expect there were stronger winds and wind slabs were releasing easily.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Light snow in the morning and then clouds decreasing in the afternoon. Winds were light along our route.

Snow surface

About 6-8" of new snow with another roughly 10" of soft snow underneath before the melt freeze crust.


We did a set of pits at 2200' and then dug another at about 2400' to try and find an area with more wind transport. In all our pits we had easy failures (ECT N 5-10) at the interface of the new snow and the old snow surface about 10" down (25cm) but no propagation. The snow on top seemed too light and loose to be able to propagate a fracture. About 16" down (40cm) there was a stout melt freeze crust with large facets on top (see photo). These took more force to fail (ECT N 25) and also did not propagate in our extended column test. These weak layers of facets are still concerning but they did not produce any interesting test results today.
