Snowpack

We dug pits on: Eldorado Bowl at 3700' on NE w HS=165cm, behind Independence Mine 3480' on East aspect and Microdot at 3990' on a SW aspect with an HS=185cm.

All pits revealed a right side up snowpack with overall good stability with the exception of weak surface snow. Surface snow consisted of 10-15cm of new snow on top of 20cm low density old snow. None of the tests had propagation.
