Snow Characteristics Comments
Much less new snow from the storm at the beginning of the week than farther north. Overall snow pack is very shallow, and off trail riding is dangerous due to the potential of hitting rocks, stumps and down logs.

Comments
I found a very loose and well developed sugary persistent weak layer. I tried several extended column test and got ECTP results on all, ranging from ECTP 6 in a very shallow area to ECTP 13 at a more average depth ~80 cm.

I went up to Providence Canyon to check out remote triggered avalanches from Wednesday. This one in lower Three Terraces Bowl (east facing around 8900') was triggered from several hundred feet away, by riders down in the flats. It was 250 to 300' wide, 1 to 2' deep and ran around 500 vrt'.
