Author: John GarnerDrive west of Amarillo on I-40 to the town of Adrian. Just past, look for the exit for FM 2858. (FM is a Texas secondary state highway). From the westbound side, you must exit, cross over, then go west on the south side access road for about a mile before 2858 branches off. It's exit 18 (I think; I forgot to write it down) off I-40. Go south on FM 2858 for a mile, then it turns 90 degrees west. Stay on it; it then turns into a county road (CR "A"), and the pavement ends. Continue west 4 miles; turn left one mile; then back right one mile to road junction with County Road R. Park at the corner. The HP of Oldham is about half a mile north and a few hundred yards west. You will need to cross over or under the fence on the west side of the road. There are no "No Trespassing" signs on that side. Walk N along the fence line, then veer W to the obvious high area. Nice views into canyon; you can see I-40 about five miles N. There is an area to the southwest that appears higher, but it is in Deaf Smith County.
