Snowpack

Snow surface all day was dominated by various sizes of surface hoar ranging in size from 5mm-2mm. Overall conditions were 8cm of dust on crust, less on southerlies.

Dug three pits throughout the day on our way up to assess snow depths and get a baseline of snowpack structure ahead of the coming storms.
Pit 1: 2300', HS:30cm, N aspect 35°
Largely faceted snowpack, ECTN23 @ 15cm down from surface. PST 32/100 SF @ 15cm down from surface on a layer of 1mm facets above a melt-freeze crust.
Pit 2: 2800', HS:100cm, NW aspect 25°
ECTX x2, right side up snowpack, pit profile below. 5mm surface hoar at this location
Pit 3: 3550', HS:100cm, N aspect 23°
ECTX, right side snowpack, pit profile below. 4mm surface hoar at this location
