Route & General Observations

I XC skied from the parking lot up the main trail around the mine building loop, then back to the parking lot. While skiing, I witness about 7-10 loose wet avalanches come off the ENE aspect of Skyscraper mountain. Each avalanche started on steep slopes (40°+).

Avalanche Details

Rain, warm temps, and slope angles were the most likely triggers for these avalanches. I have added four pictures of the avalanches. Sorry about the poor resolution, it was getting dark and all I had was an iPhone.
