Quick report
The major avalanche in Jawbone Canyon had two observed origins - release from a rock feature with steep terrain below it, and release from a wind-loaded gully that joins the main part of the canyon. In each case, crowns were observed to be between 1-2 meters, and the slide path was over 0.5 mile. Although the release area from the rock feature did not seem impressive in size, coupled with steep terrain and several pinch points in the canyon after the release created enough force to have a massive amount of snow mobilized. No major instability issues encountered during today's adventure, but the avalanche that occurred in Jawbone yesterday was major. The main canyon path was >0.5 mile of huge amounts of snow moved. The origin of the avalanche was from a release below some rock features, and a side gully also released. Wind loaded features were at extreme risk of release yesterday.
