Widespread Avalanche Activity on Silver Peak

We went to take a look at the reported widespread natural avalanche activity in the Pole Creek/Silver Peak area that occurred during the Dec 9-12 storm cycle.  We were able to see many avalanches today, we counted up to 14 with most steep terrain we encountered having slid.  Most of these likely occurred late in the storm cycle, probably sometime on Sunday Dec 11, and had 8-12'' of additional storm snow on top of the bed surface.  We were able to get close and investigate many of these avalanches, but some we were not able to access.  We found that many of these avalanches failed on the Dec 8 buried surface hoar layer and not the much deeper Dec 1 deep persistent weak layer.  These avalanches all had wide propagation and were large in size.  The Dec 9-12 storm cycle deposited 3-5' of storm snow with up to 4'' of SWE.
