Name: Zach Guy
Zone: Southeast Mountains
Route Description: Viewed from Mt. CB looking east towards Pearl Pass, Doubletop, etc, looking at the western half of the compass.
Observed avalanche activity: Yes
Avalanches: Lots of action above treeline that looks fresh, likely from the 1/3-1/4 cycle, generally on cross-drifted features from the NW winds, D2 in size. Also a lot of activity at all elevations that looks a bit older, likely from the 12/31-1/1 cycle. Only documenting the larger slides (D2), plenty of smaller ones too.
