Natural Avalanche Cycle - Upper Little Cottonwood
Comments
Travel today was East Bowl Pass to Honeycomb, with several laps down into Michigan City. There was widespread cracking, and we were able to ski cut many slopes and trigger small avalanches. There was some clearing when exiting at 12:30, and we noted a widespread natural avalanche cycle that occurred in the morning, during periods of heavy snowfall. I counted over 20 natural avalanches, with the largest being all of north-facing Grizzly Gulch, likely 1,000' wide. The avalanches were 15-30 cms deep (6-12"), failing within different density inversions, although one crown was up to 45 cms (18") deep. Avalanches were on all aspects and included several off of the south/southwest facing Grizzly Cup and Michigan City Gully, and on numerous steep test slopes.

The danger was solid Considerable during the morning hours, but new snow instabilities quickly settle out. Unless the sun comes out on Wednesday, the danger should be lower as the new snow will be less sensitive.
