General Comments

A widespread natural cycle occurred overnight 12/19 - 12/20 in the Central and Southern Bear River Range.

The avalanches mostly involved drifted snow in exposed upper elevation terrain, and some south and southeast facing slopes were involved.

This is one of the bigger sisters in Logan's Cottonwood Canyon (12-21-2010). You can still see blown-in evidence of the large natural avalanche.......

General Comments 2

The older blown-in crown on Providence Peak is from an avalanche that probably occurred in the same time-frame....
