Upheaval Dome, Geological landform in Canyonlands National Park, Utah.

Upheaval Dome is a roughly circular geologic basin about 10 km across in the Island in the Sky section of Canyonlands National Park, 35 km southwest of Moab, Utah. Its rim is a broken ring of steep, rust-colored cliffs; inside, pale cream and tan strata form concentric ridges dipping inward, with darker red-brown bands and a crumpled cluster of ridges at the eroded center. The structure is slightly elongated north to north-northeast.

The dome's origin has been debated for decades. A salt-diapir theory proposed that Paradox Formation salt pushed upward through overlying rock; a 1999 seismic study found that salt layer flat at 1,160 m depth. NASA and University of Nevada, Reno geologists mapped and seismically surveyed the structure in the 1990s, supporting a meteorite impact, and shocked quartz was announced in 2008.

Scientists and researchers regularly visit this site to study the ongoing debate between meteorite impact and salt dome formation theories.

Upheaval Dome lies 22 miles (35 km) southwest of Moab, in the Island in the Sky section of Canyonlands National Park. A trail leads from the parking area to overlooks on the rim, where the concentric rings and the fractured pale centre are visible. The surrounding terrain is desert, so carry water and sun protection.

The dome is slightly elongated north to north-northeast, and its central folds and thrust faults show bilateral symmetry along a southeast-northwest axis. Most thrusts dip northwest, suggesting material moved southeast, possibly from a meteorite arriving from the northwest. A 1999 seismic survey found the Paradox Formation salt flat at 1,160 m depth.
