Upheaval Dome Crater - The Upheaval Dome impact crater is one of the United States most famous impact structures due to its location within the boundaries of Canyonlands National Park, near Moab, Utah. The stucture is, according to the University of New Brunswick impact database, less than 170 million years old, about 10km in diameter, and exposed in sedimentary rock.
Diagnostic Evidence For This Crater
The impact origin of each location listed on this website has been supported by unambiguous diagnostic evidence of hypervelocity impact that has been reported in a scientific (usually peer reviewed) context. Without such evidence, a geological structure is not a confirmed impact crater. This section, which is included for each crater on this website, is not an exhaustive list of such published evidence, but is meant to demonstrate that appropriate work has been done for each listing.

Other significant evidence: breccia, megabreccia, morphology.
