Date of Observation: 03/27/2023
Name: Eric Murow
Zone: Southeast Mountains
Route Description: HWY 135 observations
Observed avalanche activity: Yes
Avalanches: Large avalanche ran in Red Lady Bowl – I would suspect it ran today while wind-loaded. Large natural avalanche on the easterly side of M-Face on Whestone. This avalanche appeared to break fairly deep with rocks exposed; this feature is unsupported from below.
Weather: I observed moderate wind-loading above treeline onto easterly aspects.
