Eric...most the Fossil unit is private property, only 16% public land. Some of the ranches in the unit have really good elk hunting with bulls in the 300 to 320 most common and an occasional bull 350+.
The terrain is fairly easy with pine, fir, and juniper forest in the higher elevations. Much of area east of the town of Fossil used to be Kinzua timberlands, but the mill has shut down and there isn't much left of the town of Kinzua.
I've heard that there's some real nice mule deer bucks on some of those ranches as well bear, lions, and wild turkey.
Good luck and have fun!
