2. From here you take Pipeline Road north for 7 miles (15.5 mile mark) to Ridge Road (BLM 1113).
3. From here you climb 2.5 miles up to the intersection with BLM 1114 (18 miles mark) which will be on your left at the top of a hill and has a cattle guard. You will be returning from that direction. Continue RIGHT on Ridge Road (BLM 1113)!!

7. Continue on the dirt road 279 for just under 1.5 miles (~36 mile mark) and turn right onto the north pipeline road. This road is easy to follow due to all the pipeline markers and it is mostly straight.
8. Climb the pipeline road for 4 miles to the intersection with BLM 1102 (40 mile mark).
9. Turn left onto BLM 1102 and follow in for 5.5 miles (45.5 mile mark) to intersection where BLM 1102 goes left.

11. Turn left onto 279 dirt road for 1.5 miles to the intersection with BLM 1114 (53 mile mark).
12. Turn right on BLM 1114 for 12 miles around Cabezon Peak back to the intersection with Ridge Road (BLM 1113) (65 mile mark).

Follow the directions via the numbered intersections – White Mesa Route: 1-2-3-4-6-7-8-9-10-11-12-13-14-15-16-17-18-19-22-12-11-10-9-8-7-6-5-4-3-21-20-17.
    • Note that when going down the devils backbone you must climb up the embankment at the gas line cut out to continue down the ridge. DO NOT take the switch back down to the left. On the way back you will climb these switchbacks from point 5 to point 4 (Gas line cut out) to get back on the ridge and ride the ridge in reverse. See directional arrows on the map below.
    • Finishing White Mesa (DO NOT go back to the main parking lot!!)
      • When you get back up to sign #3 on the ridge take the trail to the left around the canyon (staying on the more direct path and avoid the mess of trails off to the left) and work you way up to sign #21.
      • Once at #21 stay low to the right and take the double track road #20 down to a sharp left on to an unmarked single track that takes you over to sign #17.
      • At this point take the single track off to your right and follow it off the edge of the mesa passing the “Danger” sign. This is a very sketchy, but fun descent. Walk it if you are not comfortable!!!
      • Follow the trail all the way out. Skip the first right turn out of the ravine and continue down to the old double track and follow in back to the overflow parking lot to finish an EPIC RIDE!
    • Official Map of WHITE MESA TRAILS is located here. Look at some of the trails at the White Mesa that you will ride!   VERY EPIC!
