Geologically, it is significant because of the thick sequence of ancient rocks that are well preserved and exposed in the walls of the canyon. These rock layers record much of the early geologic history of the North American continent. Uplift associated with mountain formation later moved these sediments thousands of feet upward and created the Colorado Plateau. The higher elevation has also resulted in greater precipitation in the Colorado River drainage area, but not enough to change

neg: Riverside Mountains trending large-scale crustal extension in the Miocene, through what is known to geologists as the Colorado River Extensional Corridor. This North-South shortening is anomalous, as crustal shortening in the rest of the North American Cordillera is oriented generally East-West because of the generally East-West compression that was due to the subduction of the Farallon plate under western North America. Also unlike the rest of the North American Cordillera, deformation in the Maria Fold and Thrust Belt involved rocks of the North American Craton, most notably the Grand Canyon sequence of sedimentary rocks. The Riverside Mountains contain rocks from both the

neg: Granite Canyon Granite Canyon Granite Canyon is located in Grand Teton National Park, in the U. S. state of Wyoming. The canyon was formed by glaciers which retreated at the end of the last glacial maximum approximately 15,000 years ago, leaving behind a U-shaped valley. The canyon lies between Rendezvous Mountain to the south and Mount Hunt to the north. The trailhead for the canyon is on the Moose–Wilson Road about north of Teton Village. One of the most popular hikes from the trailhead is to Marion Lake by way of the Granite Canyon Trail which traverses the length of the canyon.

neg: Fish River Canyon national monument in 1962. Upstream, the river runs through horizontal dolomite strata; these metamorphic rocks formed part of the canyon. About 650 million years ago (Mya), plate movement formed a north-south graben, or lowered area, along which the ancient Fish River could flow and eventually erode a flat plain, which is today's upper canyon. Glaciation at around 300 Mya, part of the Dyka glaciation during the Karoo Ice Age, further deepened the canyon. About 60 Mya, South America and Africa separated (due to continental drift) and Africa rose significantly; the consequentially increased gradient of the Fish River enabled it to
