Moab Rim Trail
The Moab Rim Trail is one of the old classic "Must-Do" trails of the Moab
area. But frankly, it isn't one of our favorites. It starts with a climb that's as brutal
as anything you've ever done. If it's a weekend, you'll play "dodge-em" with a
gazillion jeeps. This is a trail you ride mostly for chest-thumping purposes. But the
views aren't bad.

high winds usher in a storm. The band at the bottom is the Potash road, with the
Colorado just out of sight. Photos

|This trail is definitely advanced technical and strenuous
aerobic. It's 10 miles as an out-and-back, and you'll climb around 1800 feet
The trailhead is on the Kane Creek road along the
Colorado, about two miles from the middle of town. Starting altitude is
4100, and the high point is 5300 at the viewpoint over the valley.
the parking area, the trail crawls around the big rocks then climbs the
bare patches left to right.
From the trailhead, the route climbs
almost 900 vertical feet in less than a mile. Near
the top, the slope is an unrelenting 20% grade, pocked with fissures, ledges, and
wheel-traps. You can usually find a side route around the big drops, but
it's brutal. Most riders will spend considerable time walking.
This is the first, and worst of two big climbs. (The second
comes right at the end on the last 0.8 miles to the viewpoint. This is 450
vertical for a 12% slope, but it feels steeper because loose moto-churn
rock chunks scattered over the slickrock messes up the traction.)

from the Colorado River with UtahMountainBiking office boss Mike
Engberson in pursuit. The rock is so rough and steep that bikers outride the jeeps,
both uphill and downhill. April 16, 2000.
|The grunt climb up the Rim is on uptilted ledges of Kayenta Sandstone. The
Kayenta is a hard layer with lots of silt in the sandstone matrix -- a sandy
mud-plain deposit where dinosaur tracks are common. The Kayenta protects the
underlying Wingate Sandstone from breakdown, allowing the Wingate to form cliffs
up to 400 feet in height.
Looking down at the Colorado River,
about 1/3 up. The cliffs at right are Navajo sandstone, with bands of
Kayenta appearing underneath at the far right.
|| At the top, the familiar mounds of Navajo Sandstone
sit on top of the Kayenta layer. On this western side of Moab, the Navajo lies
hundreds of feet higher than to the east. See our Geology
of Moab page.
Approaching the first viewpoint.
Engberson takes a break after the hard climb up from the Colorado. The La Sal
mountains are in the background. April 16, 2000.
||At this first viewpoint, you're at 4900 feet with views of
the Moab Valley both north and south. The volcanic La Sal Mountains rise
to the east.
Looking to the southwest as storm
clouds build over the La Sal Mountains.
|As you leave the first summit, the trail rolls up and down some brutal rock
outcroppings. There are short pits of life-sucking sand between bits of
rough rock. Occasionally there's smooth Navajo to ride on, but mostly it's
rough, ridged Kayenta. The terrain is very
pretty, and the views are good.
After leaving the viewpoint, the
doubletrack trail rocks up and down, with varying degrees of tech.
||The trail goes up and down, never particularly technical or
brutal. There is one steep pitch up a Navajo sandstone dome, but nothing
sustained and tough like the initial climb.
Looking over the Navajo slickrock. If
we do the full loop down Hidden Valley, we'll go through that first little
notch at the left.
The first significant trail fork is at mile 1.9. Keep
right. (Left takes you down into a sand-infested canyon where you'll have
to hike your bike up the other side.) The trail is well-marked with
crests a Navajo sandstone dome on the Moab Rim on April 16, 2000.
||At mile 3.7, the Moab Rim trail forks hard left, drops
through a little wash, then begins the steep climb to the viewpoint. This
is a grunt granny-gear climb. I found the trail surface littered with
small angular chunks of sandstone torn up by motoheads. It was easy to
loose traction. Just before the viewpoint, you'll fork right (east).
Climbing to the viewpoint, we hit more
rough Kayenta stone.
|The Moab Valley is a sunken area where fault lines
disturbed an underlying dome of salt. (This salt was deposited by periodic
flooding, then evaporation, of ocean water into a deep inland depression
called the Paradox Basin during the Pennsylvanian Era, about 300 million
years ago. It's over 1000 feet thick and is mined for salt and potash west
of Moab.) As the salt was dissolved by seeping water, the valley floor
||The fault line also changed the height of the rocks on either side of Moab.
To the west, younger rocks are exposed, with cliffs of Wingate Sandstone and
Navajo Sandstone as a cap rock. To the east, Navajo Sandstone is nearer the
valley floor, with Entrada Sandstone at the top. The displacement along the
fault occurred before the present-day Colorado River began cutting into the
rock, then the falling of the valley floor occurred later, resulting in the
unusual topography where the valley lies at right angles to the river gorge.

|Back at the trail fork, you have two options: Head back the
way you came, or fork left and uphill for the Hidden Valley Trail. The
Hidden Valley Trail forms a classic loop ride. It's very nice until you
hit a 1/3 mile section of boulder-strewn steep portage. Then you'll be
wishing you'd done the out-and-back. But if you absolutely MUST do a loop
ride, there you are.
||My recommendation is that you do the loop ride clockwise:
CLIMB the ugly portage up Hidden Valley, then descend Moab Rim. You can
close the loop by road, or you can ride the new Pipe Dream singletrack.
See the map and track files.
Heading back down from the viewpoint.
Then on to Hidden Valley for the loop.

Getting there: Head south on
Moab's Main Street. When you reach the McDonald's on your right, turn right onto Kane
Creek Blvd. After 1.5 miles, go straight at the "Yield" sign where the road
seems to turn right. Go past the Moab Rim chairlift to 3.5 miles from McDonalds at GPS N
