Quick report

Traveled to the broad bench in Herman Gulch (~5,000') via the Boulderfield. Surface snow was soft in the morning (10 cm ski pen, ~45 cm boot pen; 0900) and winds were moderate to strong with occasional extreme gusts. Wind direction was hard to determine, and we experienced both down- and up-sloping effects throughout the day. We practiced a multi-burial transceiver drill at 4,400' and observed about 50 cm of moist to wet snow on top of a crust while burying the beacons. HS was ~220 cm in this location. Snow began around 1015 and was accompanied by strong, generally down-sloping winds from Herman Saddle that funneled through the basin. Snowfall was generally moderate (S1-3) with heavier bursts, and wind slabs were actively forming as we left the field around 1115. On the drive down, we noticed snow fully transitioning to rain around 4,000'.
