From an email:
Observed a large crown in the hourglass while touring on Monday, April 14. The slide appeared to be a day or two old. We believe it was triggered by a cornice falling, looked like it broke 1-3 feet deep, and about 100 feet across. The slide went on almost a directly east facing aspect, and took out a large portion of the center of the chute. It slid through the choke, and down the apron, where in one place it stepped down to the ground level and exposed an area of rock about 20x20 ft. The debris ran the full path, well into the small saplings at the base of the chute. I wanted to get a picture and measure the depth of the debris, but temperatures were warming rapidly and I wasn't totally comfortable with the hangfire still near the crown.
