The Wallace line or Wallace's line is a faunal boundary line drawn in 1859 by the British naturalist Alfred Russel Wallace and named by the English biologist T.H. Huxley. It separates the biogeographical realms of Asia and ' Wallacea ', a transitional zone between Asia and Australia formerly also called the Malay Archipelago and the Indo ...
The geology of Wyoming includes some of the oldest Archean rocks in North America, overlain by thick marine and terrestrial sediments formed during the Paleozoic, Mesozoic and Cenozoic, including oil, gas and coal deposits. Throughout its geologic history, Wyoming has been uplifted several times during the formation of the Rocky Mountains ...
The Wyoming Basin (17) includes the Great Divide Basin. The Wyoming Basin physiographic province is a geographic area through which the Continental Divide of the Americas traverses. The province includes the Washakie Basin [1] and Great Divide Basins, and is demarcated by the following: southwest: Uinta Mountains; west: west side of Green River ...
The Big Sandy and Little Sandy Rivers northeast of Rock Springs, Wyoming, where large volumes of sand accumulated on their banks during glacial melting from the Wind River Mountains. Westerly winds that during the past 20,000 years have moved the sand eastward across the continental divide to its present location.
The fault is on the boundary of four major geologic provinces: the Basin and Range, Idaho-Wyoming Thrust belt, Rocky Mountain Foreland, and the Yellowstone volcanic plateau. The Basin and Range province is a region of east–west crustal extension. This province adds tension perpendicular to the fault line causing the fault blocks to move apart.
The wilderness spans the Montana-Wyoming border on Gallatin, Custer and Shoshone National Forests and is composed of 944,000 acres (3,820 km 2). [5] The elevation ranges from 0 to 11,000 feet (3,400 m); the maximum elevation is at the Beartooth Plateau, located high in the Beartooth Mountains.
The Sierra Madre Range is a mountain range in the western United States, located in south-central Wyoming and north-central Colorado. Geologically, it may be considered an extension of the Park Range of Colorado. South of the Great Divide Basin, the US Continental Divide runs along the Sierre Madre high points.
The east slope of the mountain is the source of the Wind River and topographic relief is modest as the summit rises 1,400 feet (430 meters) above the river in 1.25 mile (2 km). [5] Two Ocean Mountain can be seen from the Wyoming Centennial Scenic Byway which provides year-round access to the mountain except during blizzards. [ 2 ]
