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

Light winds, actively snowing, 30 degree temps.

Snow surface

6 inches of new and very dense/high moisture content snow.


Pit located on 25 degree slope on the SW shoulder of Marmot. Snowpack consisted of 6-8 inches of new, high density snow on top of 6 inches of knife-hard crust. Below the knife-hard crust is approximately 3-4 feet of cohesive isothermal/rotten snow. Two column tests were performed, neither produced a result-- no failure during normal test parameters. Both columns fractured (Q2) below the knife-hard crust when a member of the observer's group stomped on the column.
