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

Nice day! Sunny with a slight breeze. Around 25-30 degrees.

Snow surface

Dug six pits (details below). Observed 2-4 inches of light snow on top of the snow pack.


Five of the six pits had a thin, 0.5 cm melt freeze crust 20-40 cm down, and most of the tests were failing just below this crust.a Extended column tests for five pits were: ECTX (four times), ECTP4 down 20 cm on the thin crust layer, and ECTP11 at the bottom of the entire pit 115 cm down. The last pit was south facing and had a stronger sun crust near the surface and with moderate shovel pressure, the entire EC block failed at the bottom. Photos below show the 20 cm slab on top of the crust layer in two pits and the pit where the entire block failed on ECTP11.
