Great Divide Basin in the context of "Continental Divide of the Americas"

A continental divide is a drainage divide on a continent such that the drainage basin on one side of the divide feeds into one ocean or sea, and the basin on the other side either feeds into a different ocean or sea, or else is endorheic, not connected to the open sea. Every continent on Earth except Antarctica (which has no known significant, definable free-flowing surface rivers) has at least one continental drainage divide; islands, even small ones like Killiniq Island on the Labrador Sea in Canada, may also host part of a continental divide or have their own island-spanning divide.The endpoints of a continental divide may be coastlines of gulfs, seas or oceans, the boundary of an endorheic basin, or another continental divide. One case, the Great Basin Divide, is a closed loop around an endorheic basin. The endpoints where a continental divide meets the coast are not always definite since the exact border between adjacent bodies of water is usually not clearly defined. The International Hydrographic Organization's publication Limits of Oceans and Seas defines exact boundaries of oceans, but it is not universally recognized. Where a continental divide meets an endorheic basin, such as the Great Divide Basin of Wyoming, the continental divide splits and encircles the basin. Where two divides intersect, they form a triple divide, or a tripoint, a junction where three watersheds meet.

Whether a divide is considered a continental divide distinguished from other secondary drainage divides may depend on whether the associated gulfs, seas, or oceans are considered separate. For example, the Gulf of Mexico is considered separate from the Atlantic Ocean, so the Eastern Continental Divide separates their respective watersheds. But the Sea of Cortez is usually not considered separate from the Pacific Ocean, so the divide between the Colorado River watershed, which drains to the Sea of Cortez, and the Columbia River watershed, which drains to the Pacific Ocean, is not considered to be a continental divide.

The Red Desert is a high-altitude desert and sagebrush steppe located in the south-central portion of the U.S. state of Wyoming, comprising approximately 9,320 square miles (24,100 square kilometers). Among the natural features in the Red Desert region are the Great Divide Basin, a unique endorheic drainage basin formed by a division in the Continental Divide, and the Killpecker Sand Dunes, the largest living dune system in the United States. In the 19th century, the Oregon, California, and Mormon Trails crossed the Continental Divide at South Pass, just north of the Red Desert. Today, busy Interstate 80 bisects the desert's southern region while gas field roads cross the desert.

The majority of the Red Desert is public land managed by the Rock Springs and Rawlins field offices of the U.S. Bureau of Land Management (BLM). The region is rich in oil, natural gas, uranium, and coal. An estimated 84% of the Red Desert has been "industrialized" by oil and gas drilling or by mining operations and associated roads.

South Pass (elevation 7,412 ft (2,259 m) and 7,550 ft (2,300 m)) is a route across the Continental Divide, in the Rocky Mountains in southwestern Wyoming. It lies in a broad high region, 35 miles (56 km) wide, between the nearly 14,000 ft (4,300 m) Wind River Range to the north and the over 8,500 ft (2,600 m) Oregon Buttes and arid, saline near-impassable Great Divide Basin to the south. The Pass lies in southwestern Fremont County, approximately 35 miles (56 km) SSW of Lander.

Though it approaches a mile and a half high, South Pass is the lowest point on the Continental Divide between the Central and Southern Rocky Mountains. The passes furnish a natural crossing point of the Rockies. The historic pass became the route for emigrants on the Oregon, California, and Mormon trails to the West during the 19th century. It was designated as a U.S. National Historic Landmark on January 20, 1961.

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 Sierra Madre high points. Its western basins drain into the Colorado River and its eastern into the North Platte River. Buck Mountain, elevation 11,396 feet (3,474 meters), is the highest peak in the range and lies within Colorado. Bridger Peak, elevation 11,004 feet (3,354 meters), is the range's highest elevation in Wyoming.

Copper resources within the range were extracted during the late 19th and early 20th centuries by the Ferris-Haggarty Mine which lies about two miles west of Bridger Peak. Its operations were centered near Encampment 15 miles to the east. Gold findings in the range during the 1890s sparked a short-lived gold rush that attracted thousands of prospectors. The possibility of further discoveries renewed interest during the late 20th and early 21st centuries.

Bridger Pass is a mountain pass in Carbon County, Wyoming on the Continental Divide of the Americas near the south Great Divide Basin bifurcation point, i.e., the point at which the divide appears to split and envelop the basin.

The first documented crossing of Bridger Pass was by the Stansbury Expedition, returning east from an expedition to Utah and guided by Jim Bridger. A decade later the pass was in regular use by travelers on the Overland Trail and the associated stage line, these having been established along the route described by Stansbury and known since that time as the Cherokee Trail. To support the stage line, the Bridger Stage Station was established near the pass. The Overland Trail was used steadily between 1860 and 1869 until the First transcontinental railroad made the stage line obsolete.
