Limited cracking on skintrack isolation, but no shooting cracks. Handshears failing in upper part of storm snow, down 10-15cm as a F+ slab.

Light S winds with few gusts observed up to moderate. Steady temps. S-1 snow beginning at 1345h. Broken to scattered cloud cover.

Snowpack

We did not trigger any new snow slabs or dry loose on the few test slopes we traveled on. 

NW at 8400'. HS220. No propagation on either Valentine's Day interface or the Feb 8 crust.

We didn't travel on solar aspects or observe a Valentine's Day melt freeze or rime crust.  

Avalanche

1x windslab observed at a distance. D1.5 or D2 estimate since debris pile unseen over a ridge. NE 9200' and 300' wide (est) by unknown length and depth. Likely occurred during Valentine's Day loading event.
