The Moab Fault, near Moab, Utah, United States, is a well exposed and much studied geological fault. The Moab fault is an extensional fault that runs approximately NW-SE, passing to the west of the Arches National Park. It is about 45 km (28 mi) long and has a maximum displacement of about 960 m (3,150 ft). The rocks on the SW side of the fault have been lifted up forming steep cliffs of Triassic Wingate sandstone and Chinle formation. Fault damage zones have great commercial interest to petroleum geoscientists as they can dramatically affect the performance of hydrocarbon reservoirs.
