I was able to intentionally and easily trigger this huge avalanche in East Monitor along the Park City ridgeline, Utah. I was standing above where my wife is now and sanding on a 15 degree slope and hanging onto a tree. I jumped on the slope, which collapsed the very fragile layer of depth hoar and propagatated the fracture onto the steeper slope below me. My wife Susi came down to the tree after the avalanche occurred, where she watched me as I examined the fracture line of the avalanche. It is usually quite safe to examine fracture lines because all the energy has been released.
