Snowpack

We found a stable snowpack in the area we traveled. Between 2,200' and 2,500' the top 15" was very loose snow (great skiing). Under this was another 15-17" of stiffer snow (4 finger to 1 finger). This all sat on a hard melt freeze crust over the ground around a foot thick. No weakness was seen in the snow above the crust. Dug 2 pits:

Pit #1 @ 2,200' East facing, 20 deg slope, snow depth 120cm (3.5 ft)
ECTN 13 and 11 on the Solstice buried surface hoar which was intermixed with preserved stellar crystals. Layer was 40cm (15") deep.

Pit #2 @ 2,400' East facing, 34 deg slope, snow depth 145cm (4.5 ft)
ECTN 9 and 11, CT 9 on same layer, Solstice buried surface hoar which was intermixed with preserved stellar crystals
