I've not done this hike or poked around this area, but I wonder if the intersection of Roads 4670 and 210 could serve as an alternate trailhead? (map)
For those of you not on Facebook, here's the relevant portion of her post:
I almost drove right past the trail head because it looked so different. Instead of the faint remnants of a forest service road leading up into the trees, there was a freshly cut road. Confused I walked past backhoe shovels up the soft churned earth until I came upon several large pieces of equipment. I then realized that one of my favorite trails was actively being demolished. I suspect that it was becoming a victim of a local logging company. Disoriented I checked my tracking app and discovered I wasn’t on the trail. I turned around and spent almost an hour trying to orient myself amid the rubble and debris. About a mile up from the trail head I finally located an untouched portion of tread, a portion that is doubtlessly no longer in existence. The viewpoint at Burnt Granite is still there (for now anyway) and at some point some trail angels had come and cleaned out a ton of blow town near the top which eased my passage. I noticed flagging down to another ancient forest road that has since been overtaken by the trees but is still noticeable as a path. I suspect that the intent is to change the trailhead from the current one listed in the Oregon Hikers trail guide to this other road. (Gaia app has this other road labeled as National Forest Road 6310270—yes really).
