Huge slide off the face of Y mountain. My wife and I were at the park. I looked up at the mountain thinking at first it was a pillar of ice. Looking more closely we shocked to notice it was moving. First in my mind was a water fall coming over this cliff but there was no run out of water. It was huge, it finally stopped we realized it was an avalanche.

Forecaster Comment: I'm thinking it could be a wet loose slide, triggered by the afternoon sun and heating. I'll try to get more information. Evelyn
