Date of Observation: 02/14/2017
Name: Evan Ross
Aspect: North East, South East
Avalanches: R2 D2 above treeline in the northeast facing Green Lake Bowl. Looked to have run in the last couple days.
Some loose wet activity on east to south to west aspects. Nothing to impressive or surprising that I could see.
Weather: Big ball of fire with a blue background. Light northeast winds above treeline
1/10 interface was down about 25cm’s at 11,350 and down about 60cm’s just below ridegline at 12,390, both on southeast slopes. No CT result at that interface at the lower elevation, and informal hand column didn’t produce a sheer on the interface at the higher elevation. At the 11,350 pit, CTH RP on some rounding faceted particles above a melt freeze crust down 65cm. Light winds kept the snow surface mostly cool above treeline. Snow was warmed and shmoo like at near treeline elevations. By the time we were below treeline on an easterly facing slope the snow surface had already started to cool at 3pm.
Steep northeasterly slopes near 11,500 (NTL elevation) had very low density new snow over the old snow interface in some places and wind texture in others. In areas without wind texture sluffing was the main observed concern.
