Date of Observation: 11/11/2021
Name: Eric Murrow
Zone: Northwest Mountains
Route Description: East end of Baldy Mountain
Observed avalanche activity: Yes
Avalanches: From the pavement, I spotted 2 naturals along Scarp Ridge. A D2 and a D1.5 in Peeler Basin. Visibility was poor, but both avalanches appeared to only involve recent storm snow.
Weather: Partly to mostly cloudy skies. West-northwesterly winds were blasting snow into the atmosphere in the AM but relaxed and were only drifting on and off by the PM.
Snowpack: Storm totals were about 10″ at 12,000 feet. We avoided the most obvious drifted, northerly terrain features in the area, but did stomp on a few small slopes around 12K that faced north without signs of instability. No signs of instability on wind-sheltered slopes facing east near and just above treeline.

Natural avalanche on a wind drifted NE aspect along Scarp Ridge (“the shield”). Poor photo, but looking through binoculars it appeared to only involve the recent storm snow.
