As Grant and I proceeded towards Tower Mountain and Currant Creek, we noticed this natural slide near the Mill Hollow Reservoir.

This natural slide occurred on a steep northeast facing slope near the Duchesne Ridge.

General Comments 4

This human triggered avalanche broke into weak snow near the ground and shows how you can ride adjacent slopes without incident, yet trigger deep pockety slides where the snowpack is thin and fragile, especially in steep, rocky terrain.
