Travel today took us up Lee's Fork to the top of Reynolds Peak for our first run. Upon gaining the ridge, I observed a substantial crown on Mount Raymond's prominent East Face. Considering our distance, it was hard to make out the depth of the crown or the failure plane, though it looks like part of the slide went to rocks. So, it seems like this could have easily broken on our facet layer, possible that it failed on melt freeze crust facet combo. Either way, it confirmed today's forecast of High danger. It's also a good example of how natural features like trees/ rocks can connect a slab, and how slabs can break midslope.

Trigger unknown, though I imagine it was natural from the weight of our recent loading event.

Photos of Raymond: zoomed in on the crown, and the whole face for the size relative to the path.
