Notes

From obs [2/20/21]: "We observed a large natural slide on Flanders Mountain that likely occurred on Thursday (2/18/21). The crown ranged from 2-5’, but it’s hard to gauge how wide it was, because it covered a lot of elevations. I think there is considerable overlap with the large slide that ran there earlier this season. We did not observe any other slides, collapsing, or cracking, but the wind did pick up in the early afternoon."
