Wire Mesa lies just to the east of Grafton
Mesa and a couple of miles northeast of Gooseberry
Mesa. The Wire Mesa trail is an
intermediate-level singletrack loop. The loop is 7.3 miles in length, but
quicker rides can be done by using the mesa dirt road to bypass one side
of the mesa singletrack loop. There's relatively little climbing, so the
ride is easy aerobically.

The riding season for Wire Mesa is year round, but winter
access depends on recent weather. If the road is dry, the singletrack will
be good to ride. The Smithsonian Butte Scenic Byway becomes a sea of mud
after heavy rains or with late-winter thaws. Do NOT go into this area when
the road is muddy.
The Wire Mesa jeep road, looking north.
Wire Mesa has a jeep road that spans 1.4 miles from the
Smithsonian Butte Scenic Byway (the dirt road between US 9 and US 59) to
the northern cliff edge. You can intercept the trail by pedaling to
the end of the road, then walking 20 feet over the sandstone at the
cliff edge to find the trail as it circles the end of the road. Or you can
find the road for a quick return from the loop's midpoint.

The portion of the trail between the parking circle and the
end of the mesa road is 4.1 miles long. That makes a
"half-loop" using the mesa road 5.5 miles total. A bit of up-and-down
riding makes 200 vertical feet of climbing for this half loop. This
half of the loop contains most of the slickrock and tech riding.
The western side of the loop is 3.1 miles long, with most of the
elevation change near the southwest corner. This side of the loop is
mostly dirt singletrack. If you do this "half
loop" it will be a mile shorter, but will have about the same amount
of overall climbing.
If you're taking the singletrack counterclockwise, here's
how you can recognize the spot where the road will be just above you, to
1. your odometer says 4.1 miles from parking.
2. the trail makes a slow left semi-circle turn,
with a cliff to
your right and a big rock shelf to your left.
3. if you find yourself southbound a canyon ahead to your right,
you went past it.

Wire Mesa offers a combination of riding surfaces. Most of
the trail is dirt ribbon. There are some short stretches of slickrock,
usually just 30 to 40 feet, but most of the rock is stuff you bang across.
Overall, the trail is intermediate in tech requirement. It's significantly
easier than Gooseberry, and will become a favorite of early-intermediates
and mixed-ability groups.
Cruising along the cliffs heading northeast, with
Wire Valley Knoll on the right. In a half mile, we'll be riding along the
skirts of the Knoll.
In 2016, some of the trail surface is loose. Knowing the
trail was new, I rode my fat tire bike (4.8-inch tires) and floated luxuriously
where others had bobbled through slop. The fatty handled the rock
challenges nicely. (My Rocky Mountain Blizzard has a front suspension
fork, so it's a little more plush and controllable when the conglomerate
gets nasty.) My only dabs were to stop and take pictures.
On the northeast corner of the mesa, we're looking
into Zion National Park.
Climbs and descents are gentle and rarely sustained. There
are a few wash crossing down-and-ups, but I found them very easy.
On slickrock areas, the trail is marked with white paint spots on the
conglomerate. (November 2016: Marking is complete for about 3 miles of
trail at the southeast side.)
Looking to the west as the trail follows the
irregular outline of the mesa. That's the Pine Valley Mountains in the
distance, still free of snow.

Rockville to Grafton
below us and Zion in the distance.
Nice riding and nice views along the eastern side of
Great trail for a fat bike.
For now, there are no trail forks you need to be aware of.
Some alternate lines will be constructed. These will be short. On my ride,
I encountered only one completed A/B trail split.
Not easy to spot in this photo, but here's an A/B
alternate. The easy route is left of the bike (see the white paint spot
next to the tree's shadow), and the hard line is on the rock at the cliff
edge (note the red spots, which are ribbons tied to rocks).
Wire Mesa lies on Shinarump conglomerate caprock. This is
part of the Chinle Formation from the Triassic Period. The skirts of the
mesa are Moenkopi clays.
The quartzite pebbles on the dirt surfaces were river rocks that washed
down from high mountains in western Utah. Mixed with sand, they became
part of the Shinarump conglomerate. These pebbles are hundreds of millions
of years older than the conglomerate they erode out of.
On the west side of the mesa.
The mesa is mostly juniper with an understory of gooseberry
and brittle sage. There are occasional groves of pinion pine. To make
things interesting, sharp spears of yucca and stands of prickly pear may attack if you aren't holding your line on the trail.

side of Wire Mesa.

Great riding, fun for all ability levels. Fantastic views. Very much worth
doing. An excellent alternative to Gooseberry Mesa for "still
learning how to be awesome" riders.

Getting there, from Rockville: In La Verkin, turn
toward Zion National Park on Highway 9. When you get to Rockville, drive
until you're seeing the end of town then turn south (right) on Bridge
Road. Cross the Virgin River on the old bridge. Follow the road as it
veers right (west). At the fork in the road 1.5 miles later, turn left and
drive south uphill on the dirt Smithsonian Butte
Scenic Byway (may or may not have a sign). Zero your odometer. When the
road seems to level out a little 1.5 miles uphill, pass the Big Fatty Mesa
road on your right, then the Horse Valley road on the left. At 1.9 miles,
watch for the Wire Mesa dirt road on your right. Keep left at the first
fork (campsite on the right) and find the circle 0.1 miles from the Byway.

DIRT ROADS! The Smithsonian Butte Scenic Byway
will become a sea of mud after heavy rain and on warm days during a
wet winter. Always check the weather (both recent and forecast) before
driving into this area.
Getting there, from Hurricane: As you pass through Hurricane
heading east on Highway 9, turn right at the Highway 59 sign. One block
later, turn left and drive out of town. About 15 minutes later, you'll
pass a gas station on the left-hand side, then some fields. Watch for a
"Scenic Byway" sign, and turn left onto a dirt road (14.8 miles
from the turnoff in Hurricane). Two miles later, just as you reach the
mountain, the Gooseberry Mesa road turns off on your left. Keep straight
on the Byway. The road changes direction from north to east and begins
descending. At 2.9 miles from the Gooseberry turnoff, watch for a small dirt
road on the left. That's the Wire Mesa doubletrack. (If you
come to a larger dirt road forking away to the right -- the Horse Valley
Wash road -- you've gone 0.2 miles past Wire Mesa.) Go 0.1 miles to the parking circle as above.
