Snowpit Observations
More detailed information about the snowpack: 

LTCC AIARE L2 class dug several pits in same general area with similar observations. Other PST SF and ARR results below the buried rain crust, an RB7 EB that failed below this crust, and several CTM/H Q3. Consistent with observations in Echo Lakes area 2/12 and Echo Bowl 2/11.

NSF on N,NE apects where snow has remained unconsolidated at the surface, but tsurf t10 t20 at several locations show a lack of (or mild) daytime temperature gradient.

Pit: 2 additional non-reactive crusts just below last layer recorded, consistent with other recent observations
