Comments
Observed this likely natural avalanche (if not remotely triggered by Patrol) in Lake Mary Chutes from Brighton Resort parking lot at approx 0730. Guessing it went during the storm as a result of rapid loading or too heavy of load from this last storm cycle. Didn't want to poke the dragon so I didn't go out there but I'd estimate 3-4' crown, 70-100' wide, E facing. Haven't ridden Brighton in a couple years but I've never seen this face rip. Spooky because it rolled right into a terrain trap and that zone gets a lot of side country access from under prepared users. Stay safe out there.
Forecaster comments- Brighton Ski Patrol does not do any control work outside of their ski area boundaries. Speaking to Brighton Snow Safety they confirmed this was part of a widespread natural cycle that occurred outside of their boundary. If you have questions about the boundaries ask a friendly patroller.
