Travis Nauman​'s excellet observation from yesterday confirms what I'm thinking.
Although most of the usual-suspect slopes avalanched during the storm, I noticed no lack of identical-looking slopes that remain hanging, perhaps waiting for a trigger. If you must ski or snowmobile steep, shady aspects, you should do it on something that has avalanched recently and don't provoke the other slopes that did not slide during the storm. The most active slopes during the storm appeared to be "repeater" slide paths that avalanched earlier in the season and the remaining snow was thin and stayed weak due to the temperature gradient metamorphism process.
The profile I dug Wednesday on the flank of the Horse Canyon avalanche looked like a good example of a repeater slide path. The avalanche broke to the ground and on a very fragile layer of large depth hoar crystals. You can see more details in the video advisory from Thursday.
Faceted snow is one of the persistent weak layers, which makes it especially tricky and dangerous because it continues to produce avalanches several days after it's loaded with weight. Also, in my fieldwork Friday in the Abajo Mountains, I still found many areas with collapsing snow and my snow profiles were showing easily propagating fractures. (See the video.) At least for me, I would not be willing to jump into a steep slope that has not slide yet on one of the upper elevation, shady aspects. So I'll continue to call it Level 3 (orange) for a bit longer.
