This slide was intentionally triggered on a northwest slope on top of davenport hill. This happened at 1pm today. The wind was blowing north consistently about 40 mph along the ridge. I was traversing the ridge and noticed a crack propagate from my ski about 20 feet down the slope. I cautiously continued up the ridge past the initial crack when a second crack propagated from the side of my ski about 50 feet across the slope. This caused a small cornice to fall which then released an avalanche that was about 15 feet wide and ran down into trees. I estimate the slope angle was about 35 degrees at its steepest.
