South Pass (Wyoming) in the context of "Wind River Range"

The Southern Rocky Mountains are a major subregion of the Rocky Mountains of North America located in the southeastern portion of the U.S. state of Wyoming, the central and western portions of Colorado, the northern portion of New Mexico, and extreme eastern portions of Utah. The Southern Rocky Mountains are also commonly known as the Southern Rockies, and since the highest peaks are located in the State of Colorado, they are sometimes known as the Colorado Rockies, although many important ranges and peaks rise in the other three states. The Southern Rockies include the highest mountain ranges of the Rocky Mountains and include all 30 of the highest major peaks of the Rockies.

The Southern Rocky Mountains are generally divided from the Western Rocky Mountains by the Green River and the Colorado River below the Green River. The Southern Rockies are divided from the Central Rocky Mountains by South Pass in Wyoming and the drainage running east from the pass down the Sweetwater River and the North Platte River; and the drainage running southwest from the pass down Pacific Creek and Sandy Creek to the Green River. This divide between the Southern Rockies and the Central Rockies provided the lowest elevation traverse of the Rocky Mountain region for the historic Oregon Trail, the Mormon Trail, and the California Trail. The southern end of the Rocky Mountains are considered to be the Jemez Mountains and the southern Sangre de Cristo Mountains of New Mexico. Mountains south of here in N.M. are classified as the Arizona/New Mexico Mountains ecoregion using the EPA Ecoregions System.

The Great Divide Basin or Great Divide Closed Basin is an area of land in the Red Desert of Wyoming where none of the water falling as rain to the ground drains into any ocean, directly or indirectly. It is thus an endorheic basin, one of several in North America that adjoin the Continental Divide. To the south and west of the basin is the Green River watershed, draining to the Gulf of California/Pacific Ocean; to the north and east is the North Platte watershed, draining to the Gulf of Mexico. The basin is very roughly rectangular in shape; the northwest corner is at Oregon Buttes near South Pass, about 40 miles (64 km) southwest of Lander, and the southeast corner is in the Sierra Madre Range near Bridger Pass, about 20 miles (32 km) southwest of Rawlins.

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.

Pacific Creek is a stream in the U.S. state of Wyoming. The approximately 36-mile (58 km) long stream rises on the western side of South Pass and flows into the Little Sandy Creek near Farson, Wyoming. As the name implies, the stream starts just to the west of the Continental Divide and so is on the Pacific side of the divide. The waters from the stream eventually flow into the Pacific Ocean via the Green River and Colorado River. The stream is a notable landmark on the Oregon, California and Mormon emigration trails.

The Oregon Buttes are small buttes, near the Oregon Trail, in what is now the state of Wyoming.

They are just past South Pass, and are two flat-topped summits plus a smaller, conical one. For travelers on the Oregon Trail, the buttes were on the horizon for a day's travel, perhaps more. This was as they crossed Rock Creek, then Willow Creek, and, for the last time, the Sweetwater River.
