Was out on a run on the BST and saw this slide that ran from about 60 feet above the trail and buried it in about 2' of debris. Wet, hard slab with a lot of cracking spider-webbed out near the crown, ran on a bed surface of very slippery grass. Very likely triggered by a deer (see photo near crown), on a steep convex rollover above a rock band. Normally a slide of this size wouldn't be worth noting, but the proximity to the multi-use trail, slippery grass bed surface, and wildlife trigger were all interesting and worth note, especially with so many people venturing out for bench tours right now.
