Comments

I spotted this new wet avalanche in the Y Couloir on my way up LCC today. Most likely ran last night during  the heavy rain event. Looks to have run out of both arms of the couloir and left a nice debris pile of dirty snow in the apron from the prefrontal dirt storm yesterday. Thinking the high amount of rain water and the already saturated snow broke all the bonds and caused it to come unglued.

Forecaster's note: Going up and down LCC on Sunday, there was a new slide in the Y then, too, that looked like this.  I can't tell if this is the same one, and the Y does run over and over.  Evelyn
