 Was out today with excellent 16-yr old skier who is venturing more and more into the backcountry and wants to learn more about decision making and safely traveling in avalanche terrain. Besides safe travel, route selection, and rescue scenarios, we also dug a pit in Supreme Bowl. Great opportunity to look at very weak snow with some surface hoar, near-surface facets, as well as depth hoar. Have noticed that most crusts previously observed in this area have all deteriorated and at best we could find a 4F slab in the snowpack. Compression tests and ECTs could only produce disintegration of the very weak snowpack.

Am using new version of SnowPilot and included pit profile has erroneous symbols, but they should be squares (representing facets) as well as '/\' down near the ground representing depth hoar. Heard reports of finding radiation recrystallization (RR), but unable to find this.
