I'd suggest adding the distance of the turn on to FR 7020 from Bagby Hot Springs, as a double check: 1.42 miles.
We missed it, and ended up on 7030, which is much worse and closed midway up. We also ran into another hiker that also went up 7030 by mistake.

Re: Whetstone Mtn Trailhead
I have never been in that area, but since no one else responded I will try to handle this. Looking at a map it seems the turn from FR 70 onto FR 7020 is 1.4 miles past the Bagby Hot Springs Trailhead; this is the information you would like added to the Whetstone Trailhead driving directions?
