Impressive natural that appeared to have run sometime between Saturday evening and Sunday morning. Looks to have failed on January Dry Layer interface with remarkable connectivity across the slope. Estimated to be 1,000+ feet wide and 1-2 feet deep. Possibly an older and deeper crown far right in the photo. Located in the mountain range south of interstate 84.
