I tried to find this trailhead and it is no longer marked. Also, it is in the middle of the Hinckley Boy Scout Ranch and you have to trespass to access it. The Boy Scout Ranch is gated and you have to walk on their property to find the trail. There is no sign for the trail and no trail. I only found what was most likely Boundary Creek, which was dry in August 2021. Hiking along the Creek bed would be difficult due to deadfall and undergrowth. The sites mentioned in the route description no longer exist, such as Camp Frontier and Evergreen. It seems the Boy Scout Ranch is permanently closed as I would guess otherwise, it would be have been open in mid-August. There was no sign it had been open this year. I only knew I was in the correct drainage at Boundary Creek, because I checked google maps when I returned home. High Uintas Trails Illustrated map is useless in finding the access.
Good to know. The land is leased by the LDS Church, but they have recently decided to sever ties with the Boy Scouts so I don't know what's going to happen to all the LDS-run scout camps.
I used to work for Camp Evergreen and at least back then the Forest Service Lease said that they were supposed to keep access open to the trails even of people park outside the camp and walked through.
I'll call the FS and see what's going on with access.
I talked to the FS and the trail is still open, but you have to park at the gate.
Here is a 2021 video of the trail, but they only descend it.
It's too bad access has gotten worse in recent years!
