Every topo map I've ever seen showed where public land was located, I used to use them extensively before buying land of my own. If you plan to hunt some of the smaller ones be sure to ascertain their GPS coordinates and carry a GPS and topo map that shows the coordinates with you when you go. Small public parcels nearly always border private land, and landowners can be surprisingly ignorant of where their property lines actually are, be prepared to show that you aren't trespassing. In the event of a conflict call the local GW immediately and show him your topo and GPS coordinates, don't call local police who invariably side with the landowner. Such small parcels often turn out to be sanctuaries for larger bucks since they don't get hunted as much, if at all.
