Sunburst

We toured up Sunburst and skied a few runs on the front side. We noticed a large natural avalanche on the front side of Seattle Ridge as we drove up, which we think failed on the 11/16 buried surface hoar layer, just below the most recent storm snow. We also saw two fresh glide avalanches on Sunburst, one of which released while a group was skiing an adjacent slope. We dug a pit at 3200' and found two layers of buried surface hoar that we are concerned about.

Multiple glide avalanches released while we were out. Two were on Sunburst, one on Seattle Ridge. One group was skiing a slope adjacent to one of the glide avalanches when it released.

A little over a foot of light powder on the surface, down to the parking lot. There was a rain crust below this from early in the storm, which went up to around 2200'. 

We dug a pit at 3200' on a SW aspect. We found two layers of buried surface hoar, one was a little over a foot deep, and the other was around 2' deep. These were giving us mixed test results, with some tests showing poor stability (ECTP23  on a layer buried about 2' deep). We saw one large natural avalanche on the front side of Seattle Ridge while we were driving up, which looked to be about as deep as the recent storm snow layer. It was wide enough that we suspect buried surface hoar may have played a part.
