Wilderness boundaries are usually marked on main trails or trail heads entering a wilderness. A gps with a hunting gps map chip will show the boundaries and is your best bet for knowing exact land owership boundaries. www.huntinggpsmaps.com. Not all gps's will take a chip. I use a garmin oregon 450t gps.
I have the oregon 450 with a chip for Co & Wy. Whats really nice is it will show where you are in relation to these boundries...real time. You can see on the screen your location in relation to NF, Wliderness & PP boundries. If you are in a wilderness area you will see it.
