Observer Comments

Two instances of whumphing near the top of the route, around 2100' in a slightly wind affected area

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

Overcast, temps in the 20s, calm. A cloud bank sat between 1000' - 1500' throughout the day.

Snow surface

Soft snow along the surface to 2000', even under the trees along the trail. Above 2000' great spatial variability from prior wind left slabs, exposed melt freeze crusts, and even bare ground exposed both within the northern low angle bowl, and the more commonly skied NW facing face.

Snowpack

400' (parking lot): 9" of new snow
1000' (bottom of alders): 9" of new snow over 1cm surface hoar over 2" of moist melt freeze crusts
1500': 10" of new snow over 1cm surface hoar over 8" of moist melt freeze crusts/grains.
2000' (sheltered area): 10" of new snow over 1cm surface hoar, sitting on 4-finger rounds. See photo below.

Numerous hand pits from 1000-2000' would fail at the surface hoar layer, on isolation down low and under easy to moderate force higher along the route.

Pit at 2000': 20 degree slope, NE aspect, Height of Snow = 29"
ECTP7 10 inches down, failing within the 1cm buried surface hoar.
