Syncline Loop Trail Professional Reviews and Guides
"Upheaval Dome is as interesting as its name suggests, although it’s not quite correct in its description. Upheaval Crater would be a more accurate designation for the main feature around which the Syncline Loop winds. A few theories abound as to the cause of this captivating landmark, which is even visible from space: the impact crater theory and the salt dome theory. For your purposes, though, what you really need to know is that this is an incredible and unique hiking area."
--Julie K. Trevelyan , 100 Classic Hikes Utah (The Mountaineers Books).
"A long day hike or overnighter and perhaps the premier hike in Island in the Sky. This trail is the best choice for a long loop in the Island in the Sky District. With two exceptions (Neck Spring and Murphy), all other long trails in the district are out-and-back or shuttle hikes. Try for an early start, especially if you plan to cover this trail all in one day. This can be a long, hot day hike in canyon country. The hike involves one very difficult section of rock scrambling, and the NPS has posted a sign at the trailhead warning hikers about how strenuous this hike can be. That would be doubly true on a hot summer day. In any case, bring plenty of water."
--Bill Schneider, Hiking Canyonlands and Arches National Parks (Falcon Guides).
"This interesting trail traces out a loop around Upheaval Crater, an ancient crater on the edge of the Island in the Sky Mesa. The crater lies at the top of what appears to be a huge salt dome, and for many years geologists thought the depression was the result of a collapse in the center of the dome. The structure was called Upheaval Dome. New geologic evidence, however, has almost completely ruled out this theory, and now most scientists believe the pit to be an impact crater. There is usually water in the bottom of the valley, and the Park Service has also established a primitive campsite nearby for overnight hikers with backcountry permits. Trail: The trail is steep and rocky in one or two places, but well marked and easy to follow. There is usually water in Syncline Valley, 3.4 miles from the trailhead, but it must be purified before drinking."
