Syncline Loop

Distance: 8.4 miles (loop)

Island in the Sky District, Canyonlands National Park, near Canyonlands in Southeast Utah

Introduction

Heading up the Syncline Valley

Panoramic vistas are the hallmark of most hikes in the Island in the Sky district of Canyonlands National Park. The Syncline Loop trail offers a different experience. This interesting and strenuous hike loops around Upheaval Dome, descending steeply down rugged Upheaval Canyon and ascending the other side via a beautiful and challenging route up the Syncline Valley.

The trail up the Syncline Valley is recommended for experienced hikers who are comfortable climbing over boulders, scrambling up ledges and negotiating steep slickrock friction pitches. The descent into Upheaval Canyon is not as difficult but includes a steep section that loses over 1,000-ft. in just under a mile.

For hikers with the time and energy, I highly recommend combining the loop hike with a side trip to the Upheaval Dome Overlook. The 0.6 miles round trip hike from the junction with the Syncline Loop trail to the first overlook gains 120-ft. and features fantastic views of the massive crater and dome. Interpretive signs at the overlook explain the two main theories about the formation of this striking geologic feature. From the first viewpoint the trail heads northwest around the rim, ascending on easy grades to the second overlook. The hike to both overlooks is 1.6 miles round trip from the junction with an elevation gain of 200-ft.

The Syncline Loop trail is best hiked in the spring and fall when temperatures are cooler. Avoid the hot summer months when temperatures often exceed 100 degrees F.

There is little or no shade along long stretches of the trail. Get an early start and carry plenty of water. This is not a good trail for children or a good choice for the first hike in canyon country.

Looking into Upheaval Crater

Note: This trail is best hiked in a clockwise direction, descending into Upheaval Canyon and ascending the Syncline Valley. A steep section of the Syncline Valley trail requires hikers to scramble over boulders, climb ledges and scale a near vertical slab with some exposure. It is much easier to climb up these obstacles than to descend through the difficult course. The Syncline Valley also offers some shade in the afternoons, a welcome respite on the climb out.

The trail to the Upheaval Dome Overlook and the Syncline Loop starts at the northwest end of the parking area (see driving directions below). Walk up the trail for a short distance to a junction where the trail to the Upheaval Dome Overlook continues straight ahead. To the right and left is the Syncline Loop trail. Turn left (west) to hike the trail in the recommended clockwise direction.

Follow the trail as it heads west along the south side of Upheaval Dome, topping a small rise and then descending on easy grades through a landscape of desert scrub and junipers. At 0.9 miles the trail passes through a gap and begins descending into Upheaval Canyon on a series of steep, rocky switchbacks. Views open to the scenic red rock canyons to the west along with occasional glimpses of the Green River.

At 1.2 miles the grade eases a bit as the trail continues its descending traverse on a bench beside a wash. After crossing the wash at 1.6 miles the trail plummets down very steep switchbacks, some covered with scree, to the Upheaval Canyon wash, 1.8 miles from the trailhead.

The trail now travels down the canyon bottom on easy grades, alternating between walking in the wash and along its adjacent benches where the footing is better. At 3.0 miles reach a trail junction. To the left (west) is the Upheaval Canyon trail, which descends to the White Rim Road near the Green River. We take the trail to the right (north), the continuation of the Syncline Loop.

Soon the trail curves to the right (east) and quickly arrives at the confluence of two washes. To the left is the Syncline Valley while straight ahead is Upheaval Dome. Pouroffs prevent travel directly up either wash. Instead the trail crosses the Syncline Valley wash and climbs stone steps to a broad bench.

Once on the bench the trail quickly arrives at the junction with a spur trail heading into and dead-ending in the Upheaval Crater. Visiting the crater will add 3.0 miles (round trip) with an elevation gain of 200-ft. to your hike. While the hike into the crater is interesting, I personally recommend spending the time and energy to hiking the Upheaval Dome Overlook trail near the beginning of the Syncline Loop trail.

To continue along the Syncline loop turn left (northeast) and follow the trail as it ascends the beautiful Syncline Valley, initially on easy grades along the bench to the right (east) of the wash. Rising above the canyon to the west are the sheer walls of Buck Mesa while Upheaval Dome towers above the canyon to the east. Cottonwoods are scattered along wash. Depending on the time of year and rainfall you may find intermittent pools of water along the wash.

As you proceed up the valley the canyon constricts. At 4.0 miles the trail crosses to the west side of the wash and begins a very steep climb up a rocky slope, gaining over 400-ft. in 0.4 miles. This challenging part of the trail requires scrambling over boulders, climbing ledges and scaling a steep slickrock slab with some exposure. At one point along the climb a cable bolted to the wall offers a hand hold to facilitate the climb up a difficult section. Follow the rock cairns carefully through this section to stay on course.

At 4.5 miles the grade abates as the trail traverses the upper section of the canyon, traveling through grasses, brush and cottonwoods. Shade, cast by the steep canyon walls, offers a welcome relief from the afternoon sun.

At 5.1 miles the trail curves sharply to the right and soon starts climbing up a gap in the canyon’s walls, gaining 300-ft. in 0.4 miles. Cairns mark the way as the trail scales ledges, steeply ascends a slickrock chute and then climbs up a rocky section.

The rest of the hike follows a gently ascending traverse, traveling along the wash and its adjacent benches, covered in scrub, juniper and pinion pine. Turn left when you reach the junction with the Upheaval Dome Overlook trail at 7.9 miles and return to the parking area.

Hikers with additional time and energy will want to hike the Upheaval Dome Overlook trail either before or after tackling Syncline Loop. The short, popular trail offers spectacular views of Upheaval Dome and its massive crater. Interpretive signs along the way explain the two competing theories on the creation of the Dome. The easy trail reaches the first overlook at 0.3 miles (0.6 mile RT). The second overlook is a 1.6 mile round trip hike from the junction with the Syncline Loop trail.

My preference is to hike to the overlook first to avoid the crowds and gain an appreciation of the area you will be traveling around on the loop hike.
