Snow squalls were more productive than expected today. Between 1130 and 1400 hours, occasional snowfall accumulated approximately an inch of fresh snow over a variable snowpack.  It was possible to find a turn or two in light powdery snow if you searched for it. However, the majority of the snowpack on the south side of Mount Shasta hosts a variety of melt-freeze crusts, some supportable some not.  South and east-facing aspects held the most supportable crusts.
