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

Overcast or obscure skies with occasional sunny breaks and valley fog. Temperature in the 20s, calm, occasional light snow with no measurable accumulation throughout the day.

Snow surface

At 1000' - 23cm of fist hard new snow over two thin melt freeze crusts, then moist snow/additional crusts to the ground. Height of snow (HS) = 80 cm. Ski Penetration (PS) = 20 cm

At 1500' - 65cm of fist/4 finger hard new snow & buried near surface facets. This sat on the very stout Thanksgiving crust. The thin crusts observed at 1000' dissipated by this elevation. PS = 35cm

At 2000' in a sheltered location - 90cm of fist to four finger hard new snow & recently buried near surface facets over the stout Thanksgiving crust. PS = 35cm

In non-sheltered locations above treeline, HS varied from 20cm to 240 cm from previous wind transport, with 20cm - 110cm of soft surface snow depending on aspect.

A thin windslab was present in an isolated location on a more westerly aspect at the top of our route, but it didn't crack or collapse under skier weight.


Pit Result: (See photo below)
NW Aspect, 2200', 20 degree slope in a slightly wind scoured location. HS = 130cm, Foot Penetration (PF) = 42cm

Surface to 50cm: Fist to Four Finger+ hardness decomposing new snow
50cm to 60cm: Fist hard recently buried near surface facets
60cm to 120cm: Pencil Hard Thanksgiving Melt Freeze Crust over Pencil Hard Rounds
120cm to 130cm: Fist hard facets

ECTX with a test depth of 60cm (to the top of the very stout Thanksgiving layer!)
