Notes
From email "Observed a fresh slab avalanche on Mt. Henderson this morning. E, SE aspect, 9,900'. I skied up to investigate it and would estimate the size of the crown to be 2-4' deep and about 80' wide. Somewhat surprised by the size relative to the starting zone. Likely a natural avalanche (from about 36 hrs ago), but there were fresh sled tracks in the vicinity from yesterday, so possibly a remote trigger."
