Upheaval Dome Overlook Trail

Two short but steep hikes lead to overlooks of a spectacular and colorful geologic feature: Upheaval Dome. Within minutes of starting, the Overlooks trail crosses the very challenging Syncline Trail, which loops around Upheaval Dome without viewing its center. For more information about the Syncline Trail, see the Strenuous Hikes - Mesa Top to White Rim section of the Canyonlands app. Upheaval Dome first overlook Roundtrip Distance : 0.6 mi (1 km) Time : 1 hr Elevation Change : 115 ft (35m) Difficulty : Moderate Hike Description : A short but steep trail leads to a clear view into Upheaval dome. Exhibits at the end of the trail discuss this unique geologic feature. Upheaval Dome second overlook Roundtrip Distance : 1.2 mi (1.9 km) Time : 1.5 hrs Elevation Change : 114 ft (35m) Difficulty : Moderate Hike Description :This trail splits off from the first overlook trail, following cairns to more views of Upheaval Dome and Upheaval Canyon. Accessibility : This trail can be rough, uneven, and requires walking up and down a rocky hill and stone steps. It is not accessible to wheelchairs. In winter, there may be snow or icy conditions; we recommend traction devices for hikers. Dogs are not allowed on this trail . Service animals are allowed in national parks. What is a service animal? Canyonlands is a place of relative geologic order. Layers of sedimentary deposits systematically record chapters in the park's past. With some exceptions, these layers have not been altered, tilted or folded significantly in the millions of years since they were laid down by ancient seas, rivers or winds. Upheaval Dome is quite a different story. In an area approximately three miles (5 km) across, rock layers are dramatically deformed. In the center, the rocks are pushed up into a circular structure called a dome, or an anticline. Surrounding this dome is a downwarp in the rock layers called a syncline. What caused these folds at Upheaval Dome? Geologists do not know for sure, but there are two main theories which are hotly debated. Salt Dome Theory A thick layer of salt, formed by the evaporation of ancient landlocked seas, underlies much of southeastern Utah and Canyonlands National Park. When under pressure from thousands of feet of overlying rock, the salt can flow plastically, like ice moving at the bottom of a glacier. In addition, salt is less dense than sandstone. As a result, over millions of years salt can flow up through rock layers as a "salt bubble", rising to the surface and creating salt domes that deform the surrounding rock. When geologists first suggested that Upheaval Dome was the result of a salt dome, they believed the land form resulted from erosion of the rock layers above the dome itself. Recent research suggests that a salt bubble as well as the overlying rock have been entirely removed by erosion and the present surface of Upheaval Dome is the pinched off stem below the missing bubble. If true, Upheaval Dome would earn the distinction of being the
