Notes

From IG Message: “Hey guys - my partner broke off a small avalanche in super couloir today… broke full depth across half the couloir, 2-3’ deep/20’ wide and looked like it ran around 500’. No one was caught. He might message you with pictures too but here’s a video from the top”

From IG Message: “Skier triggered Pocket in super couloir. Wasn't very unexpected, the skiers left side felt a little slabbier than the skiers right and tried to stay off it but got blinded by a sick face shot. Triggered going over a sharky rock spot, not very fast moving and easy to ski out of. Snow depth was 2-2.5 feet”

Small natural avalanches below ridge South of saddle peak

Date
Activity
Skiing

Saw debris from several small natural avalanches below the ridge on an east aspect south of saddle peak while driving up to bridger. Most looked like point releases but there was one that might have been a small slab. Unsure because the light wasn't right to tell if there was a crown.

We stayed low but found a pretty uniform snowpack other than a couple of spots with sun crusts.

There was also tons of snow blowing over the ridge when we left around 3pm.

From email: "A little bbowl storm skiing for me yesterday afternoon/evening. Measured 20-25cm settled storm snow at base area and 35-40cm at mid and upper mountain. Very graupel-rich storm, with lots of rimed stellars too. Winds were blowing from the N across the lower mountain and up to the top of bridger, then I got into the calm "detachment zone" with light winds for the rest of the way. Lots of relatively soft wind slab formation going on, maximum encountered slab depth was 30-40cm. Localized cracking in these drifts, and some subtle, muffled collapsing.

I found a variable amount of "older" snow underneath the new snow, not from the Oct 17-18th storm, but from earlier this week. This was absent at the base but increased to a variable 5-20 cm on easterly aspects on mid/upper mountain."
