Description of Snow, Weather, and Avalanche Conditions:

Walking the dog this afternoon, I saw this large wet loose slide on Flagpole Peak. Not a suprise considering the new snow and rapid warm up this afternoon. I spotted this from several miles away and thus the sizes are rough estimates. I could not see any skier tracks but it's possible I missed them.
