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

Obscured and snowing a trace amount in the morning clearing to broken skies and no precip in the afternoon. Temps near freezing at the car. Winds light to moderate with gusts visibly blowing snow, and as the skies cleared the winds calmed.

Snow surface

3-5cms of new over old ski tracks at the base, higher elevations lots of spatial variability with scoured tundra, hard wind board, 20cm soft deposits and everything in between.


Hand pits at ~3400’ in SW aspect start zones showed spatial variability in depth between 20-30cms deep to a meter deep. Generally sugar snow at the base, a wind hardened layer in the middle and a softer layer on top. Did not find the rain crust in these hand pits.

Ski pole probing along the route consistently indicated hard over soft. SW aspects appeared to be leeward deposits and NW aspects appeared wind hardened or scoured.

No formal pits or tests.
