Comments
At around 8:30AM we gained Emma Ridge from Alta via the Joey skinner and as we stepped close to the rollover into Silver Fork, we remote triggered a slide about 100' wide and 10-12" deep. As it began to move, it triggered three more slides further west up the bowl towards West Bowl. One of the slides was about 200' wide and 12" deep and ran several hundred feet. Probably not overly consequential here but could be in bigger or exposed terrain.
On our descent back to Alta (south facing) anything over 30 degrees was cracking and moving until it hit mellower terrain.
All slides in new snow / crust interface. And I apologize photos aren't great. It was cold and nuking
