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

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.


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.
