Split Mountain is a 7,657-foot-elevation (2,334-meter) summit in Uintah County, Utah, United States.
Split Mountain is located 13 miles (21 km) east of Vernal, Utah, in Dinosaur National Monument and the eastern Uinta Mountains. Precipitation runoff from this double summit mountain drains into the Green River. Topographic relief is significant as the west summit rises 2,800 feet (853 meters) above the river in 1.3 miles (2.1 km). The lower east summit reaches an elevation of 7,519 feet (2,292 m). [4] Split Mountain is composed of Permian-Pennsylvanian cliff-forming Weber Sandstone with Permian slope-forming Park City Formation around the lower base. [5] The reason that the older Weber Sandstone is seemingly above the younger Park City Formation is because Split Mountain is a nearly symmetrical anticline. [6] This landform's toponym has been officially adopted by the United States Board on Geographic Names. [3] It is named in association with Split Mountain Canyon, in turn named by John Wesley Powell in 1869 as his expedition passed through this mountain which the Green River split via erosion. [7]
Spring and fall are the most favorable seasons to visit Split Mountain. According to the Köppen climate classification system, it is located in a semi-arid climate zone, with temperatures averaging between 0 °F to 30 °F in January, and 50 °F to 100 °F in July. [8] Typical of high deserts, summer temperatures can be exceedingly hot, while winter temperatures can be very cold. Snowfall is common, but the snow melts rapidly in the arid and sunny climate. Rainfall is very low, and the evaporation rate classifies the area as desert, even though the rainfall exceeds 10 inches.
Canyonlands National Park is a national park of the United States located in southeastern Utah near the town of Moab. The park preserves a colorful landscape eroded into numerous canyons, mesas, and buttes by the Colorado River, the Green River, and their respective tributaries. Legislation creating the park was signed into law by President Lyndon B. Johnson on September 12, 1964.
Dinosaur National Monument is an American national monument located on the southeast flank of the Uinta Mountains on the border between Colorado and Utah at the confluence of the Green and Yampa rivers. Although most of the monument area is in Moffat County, Colorado, the Dinosaur Quarry is located in Utah, north of the town of Jensen, Utah. The nearest Colorado town is Dinosaur while the nearest city is Vernal, Utah.
The Colorado Plateau is a physiographic and desert region of the Intermontane Plateaus, roughly centered on the Four Corners region of the southwestern United States. This plateau covers an area of 336,700 km2 (130,000 mi2) within western Colorado, northwestern New Mexico, southern and eastern Utah, northern Arizona, and a tiny fraction in the extreme southeast of Nevada. About 90% of the area is drained by the Colorado River and its main tributaries: the Green, San Juan, and Little Colorado. Most of the remainder of the plateau is drained by the Rio Grande and its tributaries.
The Uinta Basin is a physiographic section of the larger Colorado Plateaus province, which in turn is part of the larger Intermontane Plateaus physiographic division. It is also a geologic structural basin in eastern Utah, east of the Wasatch Mountains and south of the Uinta Mountains. The Uinta Basin is fed by creeks and rivers flowing south from the Uinta Mountains. Many of the principal rivers flow into the Duchesne River which feeds the Green River—a tributary of the Colorado River. The Uinta Mountains form the northern border of the Uinta Basin. They contain the highest point in Utah, Kings Peak, with a summit 13,528 feet above sea level. The climate of the Uinta Basin is semi-arid, with occasionally severe winter cold.
Paleontology in Utah refers to paleontological research occurring within or conducted by people from the U.S. state of Utah. Utah has a rich fossil record spanning almost all of the geologic column. During the Precambrian, the area of northeastern Utah now occupied by the Uinta Mountains was a shallow sea which was home to simple microorganisms. During the early Paleozoic Utah was still largely covered in seawater. The state's Paleozoic seas would come to be home to creatures like brachiopods, fishes, and trilobites. During the Permian the state came to resemble the Sahara desert and was home to amphibians, early relatives of mammals, and reptiles. During the Triassic about half of the state was covered by a sea home to creatures like the cephalopod Meekoceras, while dinosaurs whose footprints would later fossilize roamed the forests on land. Sand dunes returned during the Early Jurassic. During the Cretaceous the state was covered by the sea for the last time. The sea gave way to a complex of lakes during the Cenozoic era. Later, these lakes dissipated and the state was home to short-faced bears, bison, musk oxen, saber teeth, and giant ground sloths. Local Native Americans devised myths to explain fossils. Formally trained scientists have been aware of local fossils since at least the late 19th century. Major local finds include the bonebeds of Dinosaur National Monument. The Jurassic dinosaur Allosaurus fragilis is the Utah state fossil.
The West Temple is a prominent 7,810-foot mountain summit composed of Navajo Sandstone in Zion National Park in Washington County of Utah, United States. The West Temple, the highest feature in Zion Canyon, was originally called "Temp-o-i-tin-car-ur" meaning "Mountain without a trail" by the Paiute people. It was called Steamboat Mountain by local Mormon settlers before 1934, when the USGS officially changed it to its present name, which was applied by John Wesley Powell during his explorations in 1872. West Temple is situated two miles northwest of Springdale, Utah, one mile northeast of Mount Kinesava, and two miles west of the park headquarters. It is one of the notable landmarks in the park. The nearest higher peak is Windy Peak, 10.46 miles (16.83 km) to the north. Precipitation runoff from the mountain drains into tributaries of the Virgin River.
Mount Kinesava is a 7,285-foot (2,220 m) sandstone mountain summit located in Zion National Park, in Washington County of southwest Utah, United States.
Johnson Mountain is a 6,106-foot (1,861 m) Navajo Sandstone summit located in Zion National Park, in Washington County of southwest Utah, United States.
Nagunt Mesa is a 7,785-foot (2,373 m) mountain summit located in the Kolob Canyons area of Zion National Park in Washington County, Utah, United States.
Cathedral Mountain is a 6,930-foot (2,110 m) elevation Navajo Sandstone summit located in Zion National Park, in Washington County of southwest Utah, United States.

Mountain of the Sun is situated immediately east of Court of the Patriarchs, and south of Zion Lodge, towering 2,500 feet above the lodge and the floor of Zion Canyon. It is set on the east side of the North Fork of the Virgin River which drains precipitation runoff from this mountain. Its neighbors include The Sentinel, Mount Spry, The East Temple, and Mount Moroni. This feature's name was officially adopted in 1934 by the U.S. Board on Geographic Names.
Mount Majestic, also known as Majestic Mountain, is a 6,956-foot (2,120 m) elevation Navajo Sandstone double-summit mountain located in Zion National Park, in Washington County of southwest Utah, United States.
Checkerboard Mesa is an iconic 6,520+ ft elevation Navajo Sandstone summit located in Zion National Park, in Kane County of southwest Utah, United States. Checkerboard Mesa is situated immediately southwest of the park's east entrance, towering 900 feet above the Zion – Mount Carmel Highway. Its nearest neighbor is Crazy Quilt Mesa, one-half mile immediately west, and separated by Checkerboard Mesa Canyon. This canyon holds pools of rainwater which provide a vital source of water for resident bighorn sheep. This peak was originally named Checkerboard Mountain by the park's third superintendent, Preston P. Patraw. The landform's toponym was officially adopted in 1935 by the U.S. Board on Geographic Names. The descriptive name stems from the cliff's distinctive multitudinous check lines in cross-bedded white sandstone which give the impression of a checkerboard. The horizontal lines are caused by cross-bedding, a remnant of ancient sand dunes. The vertical and sub-vertical lines formed by the contraction and expansion of the sandstone caused by temperature changes, freezing and thawing cycles, in combination with wetting and drying. Precipitation runoff from this mountain drains into tributaries of the Virgin River.
South Guardian Angel is a 7,140-foot (2,180 m) summit located in Zion National Park, in Washington County of southwest Utah, United States.

Mountain of Mystery is situated above The Narrows, towering over 2,100 feet above the floor of Zion Canyon and the North Fork Virgin River which drains precipitation runoff from this mountain. This peak rises above Orderville Canyon on its north side, and Mystery Canyon on the south. Its neighbors include Mount Majestic, Cathedral Mountain, Observation Point, Cable Mountain, Angels Landing, and The Organ. This feature's name was officially adopted in 1934 by the U.S. Board on Geographic Names. The first ascent via the Northeast Buttress was made 15 September 2001, by Brian Cabe and Tom Jones.
Steamboat Rock, reaching an elevation of 6,074 ft is a promontory located in the eastern Uinta Mountains, in Moffat County of northwest Colorado, United States. This iconic landmark of Dinosaur National Monument is situated at the confluence of the Green River and Yampa River. Precipitation runoff from this feature drains into the Green River. This geographical formation was originally named "Echo Rock" in John Wesley Powell's 1875 report, The Exploration of the Colorado River and Its Canyons. The Steamboat name first appeared on a 1941 United States Geological Survey map of Dinosaur National Monument. The area around it still retains the Echo Park name applied by Powell during the Powell Geographic Expedition of 1869.
