Upheaval Dome is an Impact Crater in Canyonlands National Park , near the town Moab ( Utah , United States ). It is 10 Km in Diameter and the is estimated to be less than 170 million years old ( Jurassic or younger). The crater clearly visible on the surface as bright brown and black coloured concentric rings. Until about 1995 , Upheaval Dome was believed to be a Salt Dome . A salt dome is a phenomenon that occurs when salt extrudes upwards through a heavier layer of rock. In the 1990s, a team of Geologists and Seismologists from NASA and the University Of Nevada at Reno performed a detailed study that included Seismic Refraction and rock mapping. The results of this study showed that the Meteorite theory is more likely to be correct. EXTERNAL LINKS
