It’s unclear exactly when this happened, but at some point over the winter of 2021-2022 the rest of the lookout on Abbott Butte has collapsed. The lookout was included inside the boundary of the Rogue-Umpqua Divide Wilderness in 1984 and had been abandoned for awhile. The cabin was still intact as recently as 2015, when someone posted this trip report from a hike up there. Sometime after 2015 the cabin collapsed, although the tower itself remained standing. In November 2021 it was reported on Facebook that the tower was still standing. The owner of the geocache up there reported in last month that the tower had finally collapsed (photo).
This undated Forest Service photo shows the lookout in better days:
2023 update: I hiked up to Abbott Butte (see report here). It’s a nice hike, although the trail doesn’t seem to be receiving any maintenance and is overgrown. The collapsed tower was still there, but I later learned that at some point after my visit the Forest Service burned the remains, probably out of liability concerns.
