There are plenty of NF roads north of Russellville. You might go north on Hwy 7 thru Dover a few miles, then left on 164, then right on Old Hwy 7 towards Longpoll NF Campground on the Piney. But about 3 miles before Longpool take a right on the gravel/NF road and go north to an old community of Treat, where there is a low water bridge were Mocassain and Indian Creek come together. From there you can go many places: Devil's Knob, Pilot Rock, Ft Douglas, Limestone, Walnut Forks to start with.
I'm sure there are plenty of old roads, but most is ridden on a ATV or S4S, so my be too narrow. I ride dual sport motorcycles so I'm not a 4 wheeler type. But you can ride/drive for days and go nearly to Mo north, OK to west, Buffalo River east all on NF or old logging roads. You don't really need GPS tracks, just do it.
Nearly every major valley/creek at one time had a community with people living in them, Just got to dig them out.
Good Luck!
