Snow Characteristics Comments
Heavy snow today that was fairly supportable with skis on, but you would sink to the ground when you got off your sled. I stayed on the beaten path, but I saw where sleds had been badly stuck in flat terrain near the road but off the packed track.

Comments
There was evidence of a pretty widespread natural avalanche cycle that probably occurred yesterday afternoon or overnight since there was a little snow on the debris piles.
I dug test pits near the Tony Grove Road avalanches reported yesterday, right off the road on an east-facing slope at around 7500' in elevation.
