If you stay on Cleghorn Road it is all fire road. Its when you take the "illegal" trails off of the fire road where you run into what you are referring to. Regardless a stock jeep can make it through which ever way they decide to go. Last time I was up there a lot of those were in the process of being fenced off. The forest service was doing a lot of work up there. This was almost a year ago and I haven't been back since though.
