Hyalite

Skied out on an open slope adjacent to Hyalite creek today. Dug a pit on an E facing 15 deg slope at ~7800ft. No notable results in CT or ECT, but when converting to a deep tap, DT9 on the facets at the ground with a big sudden collapse. Pretty consistent with other pits I've dug up in Hyalite in the last week. Basal facets are still very weak and unconsolidated. Did not see any other signs of instability but would not expect cracking or collapsing with the problem layer buried so deep (~6 feet in this pit).
