Weather
The front moved in slow all day after the break in Feb 27th storm. Snow started again around 3:30pm. Some blue but mostly OVR-OBS. Wind near the ridges 10-15 but must evidnce of previose blow snow and the 6hr wind event (20-30)G60 night of Feb 27th.
Snowpack
We only took time to look at the new storm and wind slabs. 12K and below there is a interstorm-weak-interface in storm snow. This interface is due to the high density DF that came in early, hoever the remainder of the storm ppt was rimed stellars and groppel. This is not bonding well VE-HSx6 all aspects. The DF/Melt freeze crust interface below the HN24 (total of 25-60cm BTL and 0-60cm >TL) reacts to CT but will not propagate when provoked. No ETC. The wind event was NW-SW 6hours; creating isolate alpine wind slabs (small and large) and more unifiform depositon N-TL and BTL Storm slab 11,800-11,500 and below.
Avalanche
We saw evidence of a large slide mild-slope on the a persistent interface. R3D2.5
