^ Stumbled across your post and I see it never really got answered. Anyway, the best bet is to buy the NYNJ trail conference map set for north jersey. Its got many of those unmarked "jeep roads" on there. The Ringwood map for jorba isn't really to scale and you can get thrown off as you get to the fringe up there by Cannonball Lake. Also, FWIW, most of the marked trails in that section are hiking only trails. But, all those dirt roads are fair game. As you noticed watch out for jeeps.
