North Mamm Peak is the highest point on Battlement Mesa. It rises about ten miles southwest of Rifle, and is located in the White River National Forest. North Mamm Peak itself is really nothing more than a steep rocky outcropping rising about 300’ above the surrounding terrain. Boulder fields encircle the peak. It has a prominence of 2,451’, and an isolation of 21.2 miles.
Getting ThereFrom I-70 in Rifle, take exit 90. Go south a short distance to the second roundabout. Exit the roundabout heading east on Airport Road. Head east about 3.5 miles to West Mamm Road. Turn right, and head south several miles, where you will make a sharp right turn. Continue heading generally southwest up the road. The pavement ends after 7 miles, and turns into a good gravel road. Stay left at 9.5 miles. Turn right onto Forest Road 653 after 10.2 miles. The turnoff is located at 39.4129 N/107.7990 W. Drive a quarter mile to the end of the road. This is the trailhead at an elevation 7,820’. A passenger car can easily make the trip.
Various maps show County Road 317 heading straight south towards TeePee Park. However, the Forest Service said this road is now blocked off due to oil and gas development. The new "official trailhead" is as described above.
Route - TeePee ParkTrail 2160 begins here. Head east up the good trail to a saddle on the ridge at 9,050’. Turn left, and head due south on a faint trail. Your goal is to reach a road about a third of a mile away. We reached the road at 39.4051 N/107.8216 W. Turn right, and walk the mostly level road to TeePee Park. You will reach T intersection. Turn right, and walk a short distance west to this point: 39.3961/107.8330. There is a dirt berm on the south side of the road here. Go behind the berm, then start angling up and to the right. You will soon pick up the trail here. Climb south up the trail. The trail passes right by Point 9721 on the topo map. At about 10,000’, the trail bends to the west, and starts heading up to the top of Battlement Mesa. You’ll leave the trees here, and head out into open country, still on the trail. Take the trail to an elevation of about 10,500’. You will then have to leave the trail and start climbing towards North Mamm. We left the trail at 39.3822/107.8560. Head northwest across open country to 39.3878/107.8623, elevation 10,800’. This is just west of the small intermittent lake northeast of the peak. Work your way west to 39.3879/107.8640, then southwest to 39.3872/107.8655, then further southwest to 39.3870/107.8661. You will now be at the base of the peak, directly north of the summit. This route avoids most of the boulder fields.
See Picture 1: As you look up at the north face of the peak, you will see cliffs directly in front of you and to the left. You will see a stand of trees to your right. Climb up across the boulders, and angle to the right towards the trees. See Picture 2: Climb up to the trees shown in the picture, just to the right of the cliffs. See Picture 3: This is what you will see once you enter the trees. Climb straight up and over the fallen log in the center of the picture. See Picture 4: After you climb over the fallen log, starting looking up and to your left. You will soon see this steep Class 2+ dirt gully. This is the crux of the climb. Climb up the dirt gully. See Picture 5: This is what you will see above the dirt gully. Make the final push to the summit, where you can enjoy the views.
