This trail alternates narrow singletrack with occasional doubletrack, undulating through red and white dirt. It's upper-intermediate in technical requirement. Good bike-handling skills are required to stay off the soft shoulder and out of the cactus. Length is 6 miles. You'll do about 900 feet of total climbing, starting at 5900 feet of elevation to a peak altitude of about 6250.
The trail is located north of Red Fleet Reservoir in the Red Fleet riding area , about 10 miles north of Vernal. You'll look at some pretty rock formations as you drive to the trailhead, but you won't ride on them. This is narrow twisting dirt singletrack.
The trail is found a short distance up the J-Boy trail from the Dinosaur Tracks road. It's marked with stakes and carsonite posts. The first couple of miles are a steady climb with some up-and-down. You're riding on the red dirt of the Moenkopi formation, headed for the white of the Park City formation where most of the ride occurs. You'll be crossing three ridges as the ride plunges fairly steeply into canyons then climbs back out.
The track is narrower, and a bit more challenging, than the nearby Jass-Chrome Molly trail.

In Vernal on US-40 (the main drag), turn north on US-191. Drive to mile 10.7 and turn right at the paved road signed "Red Fleet Dinosaur Trackway." You'll cross a cattleguard and start uphill. About 1/10 mile later, find a dirt road on your left (at mile 1.6 since leaving 191). Turn into the dirt road and park. On your bike, go back to the paved road and turn left. About 100 feet later, find the singletrack marked with a carsonite sign on the left side of the road, heading north uphill just before a guardrail. Alternate: pedal uphill on the dirt road about 1/3 mile and spot Three Amigos where it crosses.
