Avalanche Details

Observed glide on SW aspect of Eddie's while climbing. Was able to see due to no cornice on the W aspect, but extent difficult to judge.

Another larger glide observed on what appeared to be Wolverine, W aspect. Pretty sure this was Wolverine and not Shark Fin.

Significant wet-loose activity on steeper slopes of Shark Fin and Tin Can from warm temps, likely day before. Many D1s, maybe a few D2s.

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

Mostly sunny, but some aspects sheltered from sun until mid-day. Temp around 30 degrees at time of observation 1130am, but was increasing rapidly. Above 40 degrees at bottom when finished.

Snow surface

Approach and very bottom slope was crust from melt-freeze. Light layer of graupel on top up to mid-elevation.
Mid elevation soft snow, didn't appear to be very wind-drifted like upper elevations, 5-8" of soft snow most of the time, except for wind blown ridges.
Higher elevations soft strastrugi and wind drifted snow.


16 degree aspect at pit location. Snow depth ~274. Most snow pencil until about 30cm from surface, then 4F, very shallow 1-2cm harder 1F top layer. ECTN12 15cm from top. Appeared to be wind slab. ECTN23 29cm from top, possibly on BSH. ECTP30 at 64cm from top, quality poor to moderate, this was absolutely on BSH (picture). This appears to be the "~2' chunk" of snow that the current forecast is concerned about.
