UFO 1- Huge storm for Provo mountains! We dug a pit an measure 30+ inches of new snow that came in upside down. I used to say I have never seen UFO 1 slide. I can no longer say that! Natural avalanche that stepped down into PWL. Huge chunks of ice and snow. The crown was along the entire south side of the bowl in the trees and cliffs.
