Mt Blackmore

Date

Skied Mount Blackmore today. There was a lot more new snow than expected (6-8") and ridgetop winds were strong and gusty. Snow along the ridgelines and on E-facing slopes was touchy. Lots of cracking and collapsing. Dug a quick pit on a SE face at 9600ft and had a reactive density change within the recent new snow about 20cm down from the surface.

Saw a natural avalanche on Alex Lowe peak just south of the Hellmouth, and 4 skier triggered slides on the E face between the Blackmore and Alex Lowe Basins. Most appeared to be wind slabs, but around 1 pm a skier remote triggered a deep slab from ~50 feet away (around the corner lookers right in the attached picture). Broke at the ground, 10-15feet deep, and took out a small tree.
