Snowpit Observations
More detailed information about the snowpack: 

Snowpack: I was probing with my ski poles all day long, and as expected, the layer of snow just above the ground was extremely variable. I chose the location I did for the snowpack because it seemed the most suspect of anywhere I traveled all day. The small natural wind slab avalanche was not far from the pit location.

The slab varied from inches to about 1' thick in a small, windloaded pocket. The debris pile was probably 30 feet from me (horizontally), and the crown 50 ft upslope. The debris did not run far as the slope was small. The bed surface was soft storm snow.
