The Sevenmile Rim trail leaves Highway 191 just north of Highway 313, about 11 miles north of town. It passes the old Cotter uranium mine and switches back to reach the cliff rim above the mine and Highway 191. The intense mining activity left a maze of core-drilling roads on the mesa top, and the trail seeks the most interesting of these. At the southern end of the rim it turns west to parallel UT 313. Along the way, Uranium Arch is visited. The trail joins other roads in the vicinity of Merrimac Butte and Monitor Butte before tucking up near Big Mesa. It passes near Determination Towers before using Tusher Pass to dip into Tusher Wash and the interesting environs beyond. Approximate mileages: 51 total, 21 off highway.
Scenery The trail route is near the Moab Fault, a geological fracture that left the trademark rocks of Canyonlands standing higher than the surrounding colorful Morrison formation. Entrada Sandstone cliffs are constantly in view. The rim views include Sevenmile Canyon, the Arches National Park area, and the Book Cliffs to the north.
Surface There is considerable two-track dirt trail, lots of slickrock, some sandy sections, a sandy washbottom, and a sandy hill near the end.
Trail Details The cliff rim portions are mainly scenic. Uranium Arch can be walked across. The south side of Merrimac Butte has exciting sidehill slickrock driving and is near Wipe Out Hill, which can be visited if there is time. The last part of the trail, if used, runs the reverse direction of the Wipe Out Hill Trail in the Tusher Canyon system, and finds easy hills of that trail to be hard, and vice versa.
Trail consisting of loose rock, dirt, and sand with some slickrock surfaces. Some erosion; washes, gulches and rock steps no higher than 18”. Tall tires(33” plus) and limited slip would be a plus. 4WD is required. Enhanced suspension travel and good ground clearance are helpful. Good driving skills a plus.
Each year we lose a few more roads/trails. Closed to us forever! It’s a horrible thought, but reality! Take a minute and think about what it would mean to you to have your favorite trail closed. One of the best ways to fight this is to practice responsible
Stay on the trail. Don’t be tempted to try a new route or obstacle. Someone will follow your tracks and soon we’ll have another unauthorized road. Go over the bumps and mud, not around them. That’s what 4-wheeling is all about.
Pack out what you pack in. If you see litter on the trail, pick it up and take it out with you. Most of all, take care of and respect this land that we love to play on.
Responsible 4-Wheeling will make a difference. Please join with the Red Rock 4-Wheelers and practice responsible
4-wheeling every day. Let’s show them that we care.
