Quick tour to the top of Avi Gully today to look for wind slabs / overall coverage in area. Below 7500' less than 1 ft of snow existed with lots of exposure and obstacles.
Notable observation from today : small wind slabs existing on N / NE aspects. Ski cuts and test slopes produced several failures ranging in depth and width. One ski cut on a 32 degree slope triggered a 8 inch slab that was approximately 10 ft. Wide and ran for 75 ft.
