Wet slide debris below Saddle Peak

Date
Activity
Skiing

Observed one pile of what looked to be fairly recent wet slide debris at the bottom of the cliffs below the Football Field on Saddle. Surprisingly, not a whole lot else of recent activity around Bridger. Seems like most things that wanted to go has already done so some days ago...

On may 6 on the Ramp there was 8-12” of heavy, mostly moist snow from yesterday. Winds were moderate to strong on the ridge and above ~7800’. Mostly cloudy.

Below the new snow, the snowpack was not refrozen. There was a very thin, 1cm crust with saturated wet snow below. There were old wet slides, d2, that ran last week out of the steep terrain south of the ramp. Wet snow avalanche potential could increase quick when temperatures get hot.

Wind slabs, wet snow below

I skied to the bottom of the ramp this morning. There was 8-12” of heavy, mostly moist snow from yesterday. Winds were moderate to strong on the ridge and above ~7800’. Mostly cloudy.

There were some fresh, hard wind slabs on the ramp. These may exist for another day or so on high, shady slopes.

From obs.: “Saw many recent looking wet loose avalanches on east facing slopes at Bridger. We got a good look at the debris pile from one in Z chute and it looked big enough to bury a person (D2) and had run far past the cat track into south bowl.

We encountered a lot of variation in ski penetration with ~1' of loose melt forms in places on north and east facing slopes ~8k' in elevation.”

From obs. “We were above the entrance to Exit Chute and triggered a slough slide that slid down one of the gullies that emptied into PK bowl. It appears to have followed an existing slide path, terminating in the top of what looked to be a significant existing avalanche runout. The slide looks pretty wide but not deep.”

On May 3 We were above the entrance to Exit Chute and triggered a slough slide that slid down one of the gullies that emptied into PK bowl. It appears to have followed an existing slide path, terminating in the top of what looked to be a significant existing avalanche runout. The slide looks pretty wide but not deep.

S1.5, winds Mod from N, OVC ~ 1400

6-8” of cold snow at Bradley’s Meadow (7,800’) but about 4-5 inches of isothermal snow and a M/F crust interface below.

if temps drop overnight, this could be a problematic layer.

winds scouring some parts of Bradley’s ridgeline and depositing 4f to 1f slabs
