Notes

We came across 2 deep slab avalanches near the typical Bacon Rind skin track. I suspect given the amount of snow on the debris, the failed on March 2nd. It is unknown whether they were triggered remotely or failed naturally. The avalanches were as large as they could be given the terrain constraints. Slope angles ranged from 29-33 degrees.

Notes

From obs: "East face of Republic Mountain above Erma Mine Cabins. 8800 ft natural avalanche just below the ridge. 3-4 foot crown, Apx 100’ across, ran approximately 1000 feet down the creek bed. Appeared to be from earlier in the morning possibly when the avalanche slid off the north face of Republic, as it had a light dusting of snow over the debris. This start zone was just over the ridge from the North facing 9:14 am avalanche but I don’t think the start zones were connected."
