Recent slab?

Date of Observation: 11/29/2021
Name: Zach Guy

Zone: Northwest Mountains
Route Description: Schofield Pass area. Traveled on W, NW, and N aspects between 10,700 and 12,500 ft.

Observed avalanche activity: Yes
Avalanches: Saw what looks like a recent slab avalanche, D1.5 in size; it failed in a west-facing cirque near Cassie Peak. It looks like it failed in older snow layers close to the ground. I’m guessing it was triggered by a very small wet loose in the past few days.
There was also a handful of previously undocumented wind slab avalanches from the last storm on NE aspects of Baldy, D1 to D1.5 in size.
Weather: Unseasonably warm, calm winds, clear skies.
Snowpack: Widespread surface hoar growth on flat or shady aspects below about 11,800 ft. Snowpack is generally faceted throughout, 1 mm near the surface and up to 3mm near the ground. It’s hard to find any lingering midpack except in previously wind-blasted terrain. We dug into a previously cross-drifted slope with no concerning pit results. In wind protected terrain, boot pen is to the ground, ski pen also getting close to the ground. West aspects were moist or wet this afternoon on near and below treeline slopes.
