Location: Cornbiscuit

Route & General Observations

Toured up to top of treeline on NW ridge of Cornbiscuit then across to the SW shoulder.

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

Warm temps in the low 30s at the trail head. Calm winds at treeline elevations but we did see some wind transport along upper ridgelines.

Snow surface

2-5 cm thick melt freeze layer on the surface up to about 2000'. It was not as thick or frozen at higher elevations so the skiing was a little better. Below 1500' the surface crust was partially frozen. We saw tons of roller balls on the surface on E, S, W aspects up to about 2500'.


We dug pits on a NW aspect at 1900' and on a W aspect at 2000'. The 1/10 layer of buried surface hoar was about 1.5-2' deep in both locations but we did not see propagation on that layer in our extended column tests. We also found another layer of surface hoar about 8" deep that I think was buried on 1/18. This layer did not have propagation in our tests either.
