Cornice Failure - Dogtooth Range

Tried to access the Wisdom Tooth via ridge walking from the back of the Ozone. Noticeably thin, faceted snow pack while bootpacking (expected). Triggered a large (school bus sized) piece of cornice which initiated while sidestepping past a small tree (see photo. Ski track closer to edge of failed cornice was us taking a look afterwards). The cornice pull back to the rocky ridge line was alarming. We tucked tail and turned around knowing that we would have to manage similar hazards the rest of the way to the tooth. Debris from the cornice made it down to the flats of the bowl entraining snow from the steep rocks below.
