Written Report:
It's always nice when these smaller spring snow storms actually result in good skiing, rather than just delaying the corn skiing. This morning there was 10-15 cm. of nice dry snow to freshen things up. I found that the wind had previously blown snow into the start zones of the Tumalo bowl (about 45 cm. of snow deposited), but I did not see any cracking or other evidence that there was a wind slab avalanche problem on this specific piece of terrain.

Temperatures on Tumalo stayed below freezing and the sun was often shining through the broken cloud cover. The wind was mostly light from the west and gusting to moderate on the top. I only saw light and isolated blowing snow, but there had been previous blowing snow from the west. By 1:30 pm slopes that had been in the sun were getting a little "smoodgy" on the surface.
