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

Temps: 25F - 38F
Wind: 10-20 mph
Sky: Patches of sun with fog and thick cloud cloud cover at times
Precip: Light flurries in the AM

Snow surface

1000'= 1/2" new snow North of the Motorized Lot, and no new snow South.
2000' = 1" new on moist crust with moist storm snow below.
3000'= 2" new snow on firm storm snow from the day before. Ridges were scoured to sun crust layer from before this last storm.


April 7th storm snow totaled between 12-20". Several storm slabs released yesterday and were visible on Common Bowl and Hippy Bowl. We did not see any new avalanche activity from today, and no other obvious signs of instability were observed.

Pit 1 - 2900' - SW aspect, 29*, HS=247cm. Showed propagation potential, but not much energy. Failure occurred at a density change between the storm snow and old snow 35cm below the surface. Results: ECTP17 (RP)

Pit 2 - 3250' - N aspect, 30*, HS=285cm, Showed propagation potential, but with little energy. Failure occurred at a density change between new/old snow interface. 57 cm below the surface. Results: ECTP28 (RP)
*Dug down 110cm and found a discolored layer at about 90cm below the surface possibly from the a dust storm that moved through our atmosphere around March 10th and 11th. Below the new storm snow we could not find any weak layer or facets within the top 110cm.
