Weather

Weather

Party cloudy with calm winds. No new snow for many days. Warmed up considerably in the pm. Air temp -1 C in shade at 1300.

Snow Characteristics

Snow surface

Thin layer of small surface hoar overlying 5 cm thick suncrust. Suncrust layer most prevalent on S. facing slopes. Loose recrystallized snow and near surface facets on lower angle slopes not affected by wind. Considerable evidence of windcrust at higher elevations.

Snowpack

5 cm thick suncrust overlying near-surface facets transitioning to rounds and rounding DH at base of snowpack. See attached snowpit profile and pic. Got CTN and ECTPV on rounding facets at base of snowpack. Lack of reaction on CT may be due to inadequate isolation of column. Got RB7 (pic).
