Snow Characteristics Comments

The new snow from Friday was quite dense with the consistency of cake flour.   We were generally on southwest facing slopes between 9-10,000'.  What surprised us was the wind effect on the snow.  There was wind crust scattered among the dense powder throughout the slopes from top to bottom.  I was out on Friday and there was very little wind and there wasn't much wind today, but it must have been windy last night to have made such a significant change to the low density snow that fell Friday.

Generally these southwest facing slopes seemed pretty bombproof with about a foot of dense snow on top of a very firm layer of snow. We didn't dig a full pit, but the overall snowdepth was not more than about 48" and there were plenty of rocks still poking out of the thin pack on these southerly slopes. The coverage was slimmer than I expected for this elevation. However, there were windslabs from cross-loading in many gullies and other locations. We didn't see any movement, but I would think some small pockets could pull out in the right situation. The underlying snow did not seem like it would become involved.
