To Put it Bluntly...

Some very large - up to size 3, avalanches in the Seaton / Blunt Range area. We saw 4 different slabs, generally on alpine north through east facing slopes. These were likely triggered by falling cornices. One large 2.5 slab was out of a south east aspect and may have occurred during warming today. We suspect the others occurred during the sun and warming on Monday. What was really impressive was the wide propagation - up to 500 m wide for one of the avalanches. We think the failure plane was the persistent weak layer described in the bulletin. We stuck to mellow alpine slopes and managed to find some beautiful skiing while avoiding overhead hazard from sunny slopes and cornices. The snow surface was moist due to warming below treeline, and steep sunny slopes will likely have a new sun crust after today.
