This is a fun dirt singletrack located near Red Fleet Reservoir north of Vernal. Ridden as described below, it's 6.5 miles. Lowest elevation is 5700 feet. While there's only 300 feet of absolute elevation change, up-and-down riding will make your climbing about 800 vertical. We're bombing south down a ridgeline trail in white clay, headed toward the deep reds below. Photos September 27, 2007. |
| The trail is intermediate technical, but the quick uphills after wash-crossings are
more fun if you're an expert and can plunge with speed.
The trail begins in the deep red dirt of the Moenkopi formation. The trail itself is firmly packed, but the shoulder is soft. If you bobble off-trail, you'll dig in, and likely dump. In many spots the trail threads through clusters of small cactus. You definitely want to stay on-trail. |

The first part of the ride is up and down -- mostly up. As you climb, you hit the phosphate-rich white clay of the Park City formation. The riding surface is more firm here, but it's also rougher if cow-prints have fossilized. Typical trail segment in the red dirt, weaving through juniper and sage. |

This area is BLM rangeland, serving a lot of cows. There are
two critical turns at water troughs. At these spots, tramping cows may
make the trail hard to see. Sticks and rocks have been placed to mark the
trail, but they're easily knocked aside by the cows.
Cattle watering trough, served by the small pipe you see here. You visit this trough twice, once from each side, as you start and complete the big loop.

| At the top elevation of the ride, you'll dip through a bunch
of gullies. The trail branches a bit here as riders have sought alternate
lines. Just keep heading east (generally along the fenceline). The trail
will turn suddenly south and begin a very fun downhill romp.
At the top of the ride, we're about to plunge steeply between these junipers, then rocket up the other side of the gully! |

| Getting there: 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. The trail starts on the west side of the parking area (left as you pulled in).

Camping and activities: Red Fleet State Park (fee required) is just a couple of miles away. Camp on the shore of Red Fleet reservoir in improved campsites. Water. Boat launching ramp. Red Fleet is a pretty lake surrounded by Navajo Sandstone. Water sports, bass fishing, scuba (Vernal has a dive shop). View of Red Fleet from the Dinosaur Trackway Trail |
| A fun activity for families is the Dinosaur Trackway hike. No bikes allowed. It's a two-mile round trip from the trailhead. The trackway is on a mudstone slope that banks down to the shore of Red Fleet Lake. The trail has numbered markers, presumably for an interpretive trail, but as of September 2007, there are no signs or pamphlets at the trailhead. But there is a bathroom. |
