Route & General Observations

Three Alaska Avalanche School groups toured up for field observations today at Tincan Backdoor, Cornbiscuit and Sunburst. Noticed a bunch of small avalanches both from yesterday mid storm, one new one on looker’s right steep Eddie’s shoulder, two new ones at base of Goat Couloir, numerous new wet loose point releases along Goat Ridge from today, some wet loose evidence from yesterday in gulleys off E. Seattle Ridge…but overall noted that there were a ton of stability testers out today and saw no human triggered instabilities.

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

Today felt like the first Spring like day with clear sunny skies and a noticeable warmth to the sun (as felt evidently as well by the snow). Temps were around the mid 20's, winds were calm.

Snow surface

A large variety of wind textures ranging from soft sastrugi to wind sculpted harder snow to snow drift deposits: definitely fast/slow/fast/slow skiing.


All three groups went hunting for the Buried Surface Hoar (BSH) and none was found. The only interface that was providing any results in CTs (and just 1 solo ECTP22) was 20 cms down on top of the old wind slab. Under the lens, it looked like more decomposing stellars. Pit pictured below from Snowpilot was on Sunburst NW 2100', 28 degree slope where the ECTP occurred.
