Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.
Weather

Mostly sunny, cold (0F) at ridgetops and windy. Sustained 15-20mph westerly winds.

Snow surface

1800 - 2800' : 6" low density powder on supportable crust.
2800 - 3500' : Variable. Sunburst west ridge is totally scoured to firm wind board and sastrugi, making for easy boot packing. Pockets of 2'+ soft wind slabs on N aspects. Once away from the wind-scoured ridge, surface softens up dramatically on the decent.

Snowpack

High strength, low to moderate energy and a generally good structure* found in test pits.
Pit #1: HS 215cm @ 3550', West aspect, Sunburst.
ECTP26 down 30cm on 3-5mm buried surface hoar*.
ECTN24 on same layer.
Pit #2: HS 150cm @ 3200', SE aspect.
ECTX. No surface hoar found in this pit.

*A note on the buried surface hoar: Though a bit of a surprise to find today (likely deposited Thursday night/ Friday morning), this layer showed high strength and propagated in 1 of 2 ECT's. SH was not found in second, lower pit and likely 'pockety' in nature.
