The Oregon Trail was a 2,170-mile (3,490 km) east–west, large-wheeled wagon route and emigrant trail in the United States that connected the Missouri River to valleys in Oregon. The eastern part of the Oregon Trail spanned part of what is now the state of Kansas and nearly all of what are now the states of Nebraska and Wyoming. The western half of the trail spanned most of the current states of Idaho and Oregon.
The Continental Divide National Scenic Trail is a United States National Scenic Trail with a length measured by the Continental Divide Trail Coalition of 3,028 miles (4,873 km) between the U.S. border with Chihuahua, Mexico and the border with Alberta, Canada. Frequent route changes and a large number of alternate routes result in an actual hiking distance of 2,700 miles (4,300 km) to 3,150 miles (5,070 km). The CDT follows the Continental Divide of the Americas along the Rocky Mountains and traverses five U.S. states — Montana, Idaho, Wyoming, Colorado, and New Mexico. In Montana near the Canadian border the trail crosses Triple Divide Pass.
James Felix "Jim" Bridger was an American mountain man, trapper, Army scout, and wilderness guide who explored and trapped in the Western United States in the first half of the 19th century. He was known as Old Gabe in his later years. He was from the Bridger family of Virginia, English immigrants who had been in North America since the early colonial period.
The Platte River is a major river in the State of Nebraska. It is about 310 mi (500 km) long; measured to its farthest source via its tributary, the North Platte River, it flows for over 1,050 miles (1,690 km). The Platte River is a tributary of the Missouri River, which itself is a tributary of the Mississippi River which flows to the Gulf of Mexico. The Platte over most of its length is a broad, shallow, meandering stream with a sandy bottom and many islands—a braided stream.
South Pass is the collective term for two mountain passes on the American 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-impassible Great Divide Basin to the south. The Pass lies in southwestern Fremont County, approximately 35 miles (56 km) SSW of Lander.
The North Platte River is a major tributary of the Platte River and is approximately 716 miles (1,152 km) long, counting its many curves. In a straight line, it travels about 550 miles (890 km), along its course through the U.S. states of Colorado, Wyoming, and Nebraska.
The Wind River Range is a mountain range of the Rocky Mountains in western Wyoming in the United States. The range runs roughly NW–SE for approximately 100 mi (160 km). The Continental Divide follows the crest of the range and includes Gannett Peak, which at 13,802 ft (4,207 m), is the highest peak in Wyoming; and also Fremont Peak at 13,750 ft (4,191 m), the third highest peak in Wyoming. There are more than 40 other named peaks in excess of 12,999 ft (3,962 m). With the exception of the Grand Teton in the Teton Range, the next 19 highest peaks in Wyoming after Gannett are also in the Winds.
The Sweetwater River is a 238-mile (383 km) long tributary of the North Platte River, in the U.S. state of Wyoming. As a part of the Mississippi River system, its waters eventually reach the Gulf of Mexico.
The California Trail was an emigrant trail of about 1,600 mi (2,600 km) across the western half of the North American continent from Missouri River towns to what is now the state of California. After it was established, the first half of the California Trail followed the same corridor of networked river valley trails as the Oregon Trail and the Mormon Trail, namely the valleys of the Platte, North Platte, and Sweetwater rivers to Wyoming. The trail has several splits and cutoffs for alternative routes around major landforms and to different destinations, with a combined length of over 5,000 mi (8,000 km).
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 the United States 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/Atlantic Ocean. 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 Laramie Plains is an arid highland at an elevation of approx. 8,000 feet (2,400 m) in south central Wyoming in the United States. The plains extend along the upper basin of the Laramie River on the east side of the Medicine Bow Range. The city of Laramie is the largest community in the valley. The plains are separated from the Great Plains to the east by the Laramie Mountains, a spur of the Front Range that extends northward from Larimer County, Colorado west of Cheyenne. The high altitude of the region makes for a cold climate and a relatively short growing season. Unsuitable to most cultivation, the plains have historically been used for livestock raising, primarily of sheep and cattle.
The Cherokee Trail was a historic overland trail through the present-day U.S. states of Oklahoma, Kansas, Colorado, and Wyoming that was used from the late 1840s up through the early 1890s. The route was established in 1849 by a wagon train headed to the gold fields in California. Among the members of the expedition were a group of Cherokee. When the train formed in Indian Territory, Lewis Evans of Evansville, Arkansas, was elected Captain. Thus, this expedition is sometimes written as the Evans/Cherokee Train. In 1850 four wagon trains turned west on the Laramie Plains, along Wyoming's southern border to Fort Bridger.
The Bridger Trail, also known as the Bridger Road and Bridger Immigrant Road, was an overland route connecting the Oregon Trail to the gold fields of Montana. Gold was discovered in Virginia City, Montana in 1863, prompting settlers and prospectors to find a trail to travel from central Wyoming to Montana. In 1863, John Bozeman and John Jacobs scouted the Bozeman Trail, which was a direct route to the Montana gold fields through the Powder River Country. At the time the region was controlled by the Sioux, Cheyenne and Arapaho, who stepped up their raids in response to the stream of settlers along the trail.
The Emigrant Trail in Wyoming, which is the path followed by Western pioneers using the Oregon Trail, California Trail and Mormon Trail, spans 400 miles (640 km) through the U.S. state of Wyoming. The trail entered from Nebraska on the eastern border of the state near the present day town of Torrington and exited on the western border near the towns of Cokeville and Afton. An estimated 350,000 to 400,000 settlers traveled on the trail through Wyoming between 1841 and 1868. All three trails follow the same path through most of the state. The Mormon Trail splits at Fort Bridger and enters Utah, while the Oregon and California Trails continue to Idaho.
Union Pass is a high mountain pass in the Wind River Range in Fremont County of western Wyoming in the United States. The pass is located on the Continental Divide between the Gros Ventre mountains on the west and the Wind River Range on the east. A triple divide exists nearby, where water may flow to the Mississippi River, Columbia River, or Colorado River. The pass was historically used by Native Americans and early mountain men including the Astor Expedition in 1811 on its way west. On the return trip, fearing hostile Indian activity near Union Pass, the Astorians chose a southern route and discovered South Pass.
The Overland Trail was a stagecoach and wagon trail in the American West during the 19th century. While portions of the route had been used by explorers and trappers since the 1820s, the Overland Trail was most heavily used in the 1860s as a route alternative to the Oregon, California, and Mormon trails through central Wyoming. The Overland Trail was famously used by the Overland Stage Company owned by Ben Holladay to run mail and passengers to Salt Lake City, Utah, via stagecoaches in the early 1860s. Starting from Atchison, Kansas, the trail descended into Colorado before looping back up to southern Wyoming and rejoining the Oregon Trail at Fort Bridger. The stage line operated until 1869 when the completion of the First Transcontinental Railroad eliminated the need for mail service via stagecoach.
Fort Halleck was a military outpost that existed in the 1860s along the Overland Trail and stage route in what was then the Territory of Idaho, now the U.S. state of Wyoming. The fort was established in 1862 to protect emigrant travelers and stages transporting mail between Kansas and Salt Lake City, Utah, and named for Major General Henry Wager Halleck, commander of the Department of the Missouri and later General-in-chief of the Union armies.
Howard Stansbury was a major in the U.S. Army Corps of Topographical Engineers. His most notable achievement was leading a two-year expedition (1849–1851) to survey the Great Salt Lake and its surroundings. The expedition report entitled Exploration and survey of the valley of the Great Salt Lake of Utah, including a reconnaissance of a new route through the Rocky Mountains was published in 1852 providing the first serious scientific exploration of the flora and fauna of the Great Salt Lake Valley as well as a favorable impression of the members of The Church of Jesus Christ of Latter-day Saints, who had settled there beginning in 1847.
The Platte River Crossing, also known as Bennett's Crossing, is the point at which the Overland Trail crossed the North Platte River in Carbon County, Wyoming. The site is a natural ford created by an island in the middle of the river with a firm river bottom on either side. The location was used as a ford by Native Americans before the arrival of Europeans in the West. The first Europeans to use the site were members of the William Henry Ashley fur-trading expedition of 1825, followed by John C. Frémont in 1843. In 1850, Howard Stansbury camped at the site, noting the presence of remnant Native American encampments around the site. By the time the Overland Stage Line was established in 1861, the crossing had been used by emigrants for several years. In later years, a ferry was operated at the site by Ed Bennett, leading to the site becoming known as Bennett's Crossing. When the Union Pacific Railway laid tracks through the region in 1868, the crossing fell out of use.
Split Rock, also known as Twin Peaks, is a mountain in the Granite Mountains of central Wyoming. The peak has an elevation of 7,305 feet (2,227 m), and is located about 10 miles (16 km) north of the Muddy Gap junction between Casper and Rawlins. The mountain is distinctive for a deep V-shaped cleft dividing its summit. The mountain was a prominent landmark on the Oregon Trail and other early settlement routes in the region, which crossed a low rise at the eastern end of the range between Casper and the North Platte River valley and the Sweetwater River.
