=====================================================================================
Remarks:  Dug many snowpits the previous day.  Rutschblock tests on S-facing
slopes revealed significant potential for slab sliding on old depth hoar near
the ground.  On N-facing slopes the entire column was loose and sugary in 
texture. This was the weekend after cold weather associated with a storm that 
produced 6 - 9 inches near the Laramie Range but very little accumulation in 
the Snowy Range.
