I have seen a few in the upper monument area.
Head West out of town, then take a right on Knight road. You will come to a 4-way intersection, go strait. The road becomes Pothole Rd. at that point.
Take a left on Pine Forest Rd.
Then go right on Cedar Valley RD.
The road will make a hard left, short strait, then a hard right.
After that hard right, keep going strait. You will see a dirt road that keeps going strait, while Cedar Valley RD. turns left. Stay strait. That is Monument Rd.
Follow it for a few miles, and you will come to a "Y" in the road, go to the right. There used to be a road sign (Cannot remember what it says) on the road you want. If you stay on that road long enough, you will come to an old bunk house, corral, etc. There is a good spring right there. You can go up the hill on roads on each side of the corral area. It makes a loop with one road taking off of that loop and going all the way to the top of the ridge at the indian reservation boundry.
If you go, let me know how the area looks. I havent hunted that area since my honeymoon in 2004.

(yes, went hunting on our honeymoon!)
