Wind Deposition and Scour on Buck Ridge

Date
Activity
Snowmobiling

Saw this cool illustration of wind deposition, scouring and unaffected snow on a ridge line near the top of Bear Creek at the far end of Buck Ridge.  The lighting really helped too.  Ridge top is scoured and piled onto the lee slope and there is a very clear line between hard wind slab and relatively unaffected snow where the old snowmobile tracks are.  

We also spotted a small, snowmobile triggered avalanche on a steep, east facing slope in Muddy Creek.
