The subduction of the Farallon Plate beneath western North America remains a poorly understood event, although new seismic and computer tomography modeling is shedding light on the event. The widespread uplift then carved them up to the west and in the Black Hills, which caused rivers to drain the highlands, eroding the landscape. Subsequent erosion has generated large caves in the limestone, including Kartchner Cavern in Cochise County and the Grand Canyon's Vesey's Paradise.
