Route & General Observations

We skinned up the ridge east of Delia Creek, and after getting stopped by a sketchy knife edge section we descended an east facing slope (~35 deg) into the adjacent valley to continue that way. On the descent, I triggered a 4-6″ slab, which ran for a hundred feet or so. No burials.
