Comments
Snowpits showed total depth around 3'-4' depending on location and elevation. Some north-east facing slopes were less than 2' deep and made up of mostly faceted snow. In the above pit which did have a slab of 1F and 4F snow above the facets, we were able to get results with compression tests in the teens. In other snow pits on north-east facing slopes with less snow we were getting failure with isolation on a crust/facet combination near the ground.

Photo of a series of avalanches on an east-southeast facing slope at 10,500'. Some ran on facets near the ground and the lower right slide ran more recently (perhaps today) on a dirt layer.
