Summary of avalanches reported from highway and resort control work:
There were numerous large avalanches from morning highway control work on the southerly facing slopes above Little Cottonwood, including the White Pine, Little Pine, Monte Cristo, Superior, Hellgate, and Toledo slide paths.
Ski area activity, explosive triggered, included Class 3’s in uncompacted terrain, the largest reported 4 to 8’ deep by 700 feet wide. 1 to 2’ deep slides were triggered with explosives at cliff bases where graupel had pooled. Hard Slabs 1 to 3 feet deep were triggered on east facing terrain.
Natural activity was spotted on several ESE facing slopes on the Park City ridge line.
