Snowpit Observations
More detailed information about the snowpack: 

Conditions in the BWRA today were a continuation of the warm and mostly sunny weather seen over the past 10 days.  Winds were a bit stronger and high clouds filtered out the most intense solar radiation.  The clouds and winds also prevented melting of the snow surface on most non-southerly aspects.  A thin sun crust was present on east facing aspects as well as some northerly aspects.  I dug a snowpit on a east facing, 34* slope at 10,200' in the PCT crossing area.  The snowpack here was mostly uniform with 1-finger to pencil hard rounded grains capped by a melt-freeze crust-wet snow-sun crust combo in the top 5 cm.  As expected, stability tests did not reveal anything of concern.  Even though it has been warm for the past 10 days, most non-solar upper-elevation slopes contain 99% dry snow, with wet snow only present on the surface during the afternoon.  A winter time snowpack is still present in most areas throughout the BWRA.
