Southern Gallatin

Big Sky ski patrol triggered these slides with explosives on 11/22 during routine avalanche mitigation work. The avalanches were hard slabs that averaged 12" deep and broke on a weak layer above a crust on top of snow that fell in October. Photo: BSSP

Lick Creek Snowpack

Date
Activity
Skiing

First tour out in Hyalite today and thought I'd share some quick data I gathered from the Lick Creek saddle.

50-60cm of snow out there with hardly any wind effect on it. 

The quick pit I dug was:

0-25cm F 1-1.5mm faceting rounds

25-27 1F solar crust (easily broken)

27-43 4F 1mm rounds

43-55 F new snow

Cheers!

Cracking in a drift at Bridger Bowl

Date

An observer saw evidence of wind loading creating the conditions for avalanches in the Bridger Range on Sunday. Cracking is an indicator of instability. The observer noted that the relatively small drift he saw was "nothing consequential," but this shows that unstable drifts are forming. They will be more consequential where there is more snow and as the wind creates larger drifts.

Temperatures to mid 90s F expected for the next week. We may see the season's first snowfall as early as 3-4 weeks. There is minimal snow remaining at the highest elevations. Avalanche danger seems low.

From 5/21/22: "Triggered a small slide underneath the cornice of the southeast chute off of Emigrant peak. The slide was 50 ft wide,  4 inches deep, and ran for about 100 ft. The slide was not large enough to knock you off your feet (D1). The latest storm had deposited about 12 inches of new snow underneath the cornice." Photo: C. Chupik
