Observation: Summit

Location: Summit Road Obs

Route & General Observations

Drove through Summit between 2:30 – 3pm to look for recent avalanches post New Years Storm. Found evidence (debris and filled in crowns) from numerous D2 (large) avalanches. These were all on South to West aspects.

Unusual wind loading patterns were noticeable on the far Southern end of Summit Lake. The South facing slopes of Tenderfoot and Butch were scoured to the ground. East aspects looked to have more coverage than their usual wind scoured look, but couldn’t see many of East facing slopes from road level.

Many Northern aspects across the entire Summit zone were visually wind scoured and thin and West aspects looked pretty fat and loaded – which is typical.

The snowpack looks visually thinner on the far Southern end of Summit Lake near Tenderfoot compared to the Northern side near Moose Mt.
