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.

Numerous wet slides on south and west aspects.

Heavily sun affected on east, west, and south aspects. About 6-8" of dense, dry snow on north, shaded aspects.
We dug a pit at the head of the valley on a north aspect (~40 deg) and did two ECTs, getting ECTX twice.
