Slide on Broken Top/Bend Glacier
There was a large R4D3 slide on the NE aspect of Broken Top that I was able to get a glimpse of after topping out on the ridge of Broken Top looking down on the Bend Glacier. The crown appeared to be >600' wide, and several feet deep in places, and the slide ran ~1000 vertical feet, well into the low angle runout zone. I don't know what the trigger was, but given the size, aspect and lack of natural activity elsewhere, I wonder whether it was triggered by cornice fall. From one vantage point it looked like the slide stepped down to deeper layers, but it was difficult to tell since I wasn't able to (and didn't want to) drop down on the NE side to get a closer look. There didn't appear to be much new snow covering the debris, so it likely ran towards the end of the last storm cycle.
I wasn't able to get the entire slide with one photo, but have a few shots showing each side of the crown as well as the length of the runout.
