This is a scenic ride in the Red Fleet mountain biking area just north of Red Fleet Reservoir in the Vernal area. It has some taxing climbs, so attack this one while you're fresh. It requires advanced technical skills. The singletrack is 2.6 miles, with pavement closing the loop for a total of 3.2 miles. Dirt options include riding the part (or all) of the Jazz Chromoly trail as your return route.
You can also link to Jazz Chromoly for a longer dirt loop, but I don't recommend this unless you either adventurous, following a GPS track, or riding with somebody who knows the area. (The track files for the Red Fleet area include waypoints and tracks where these alternate connectors hit the paved road.)
At the next trail fork, keep left and veer southwest to stay on Handsome Cabin Boy as J-Boy continues northwest.

4.3 Back at parking
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." Drive uphill 0.6 miles. At the top of the hill, turn left onto a dirt road and immediately park in the wide area on the left. On your bike, go back to the paved road and turn left. 100 feet later, find the narrow singletrack on the right side of the road, heading south.
Alternate, cattle grate: Drive to the cattle grate at mile 1.5 and park in the small spot on the right side of the road. Find HCB southbound along the fence and follow it until it crosses the road again.
Alternate, J-Boy: Drive to the Dinosaur Tracks parking area at mile 2.4 then take J-Boy either direction to HCB.
Bathroom:
2.4 miles from US-191 on the Dinosaur Trackway road is a bathroom at the
the trackway trailhead. No water.
