Date of Observation: 12/07/2022
Name: Zach Guy Evan Ross
Zone: Northwest Mountains
Route Description: Washington Gulch
Observed avalanche activity: Yes
Avalanches: Lower Washington Gulch: A few small natural persistent slabs that likely ran last night on the small, steep slopes near Meridian Lake.
Gothic Mountain W-NW: This area has seen a few avalanches recently. A couple of D2 on NW and a couple of D1’s on W. Probably ran last night or yesterday during a loading event. Not really any snow or wind today so I wouldn’t expect they ran this morning.
Elkton Knob W-NW: Several small to large slabs that ran on NW to W aspects. They all had snow on the bed surfaces and likely ran last night or yesterday.
Mt Emmons: NW aspect in Wolverine Basin. Couldn’t see debris or accurately judge size from such a distance. At least large in size.
Mt Baldy South Bowl: Looker left side of the south bowl had a large avalanche. SE aspect. The avalanche debris looked soft with fresh snow on them. D2.5
Mt Baldy South Bowl. SW aspect with a notable crown but the avalanche was small in size. D1.5
