Quick report

The only instability that we witnessed was evidence of an avalanche (with a 6 to 10 inch crown) at mid mountain on Granite on a north east aspect at 7300 feet that appeared to be rider triggered over the weekend with a little bit of new light snow masking the avalanche.

Mostly cloudy to foggy... few inspirational breaks in the clouds with sunshine and blue, but overall fairly light SW winds and very light snowfall-stellars with fof moving in towards the end of the day!

Snowpack

We did not get propagation in any of our snowpit extended column tests and the structure was mostly right side up and similar on both aspects. We had graupel, rimed particles, and fresh stellars on the surface. 7-8 feet of snow on the ground (2+meters) ...We also did not observe any persistent weak layers in our failures however, Mid pack , we did have a prominent grapple layer that lack propagation also.
