The Gates of Lodore is the scenic entrance to the Canyon of Lodore, a canyon on the Green River in northwestern Colorado, United States. [1] The name Gates of Lodore has become synonymous with the canyon itself and the two names are used interchangeably. The Canyon commences as the Green River departs Browns Park and cuts through the Uinta Mountains meandering eighteen miles until its end at Echo Park (Colorado), the confluence of the Green and Yampa River. [2] It was named by the Powell Expedition after the English poem Cataract of Lodore . [3] It is located in Dinosaur National Monument.

The Green River, located in the western United States, is the chief tributary of the Colorado River. The watershed of the river, known as the Green River Basin, covers parts of the U.S. states of Wyoming, Utah, and Colorado. The Green River is 730 miles (1,170 km) long, beginning in the Wind River Mountains of Wyoming and flowing through Wyoming and Utah for most of its course, except for a short segment of 40 miles (64 km) in western Colorado. Much of the route traverses the arid Colorado Plateau, where the river has carved some of the most spectacular canyons in the United States. The Green is slightly smaller than Colorado when the two rivers merge but typically carries a larger load of silt. The average yearly mean flow of the river at Green River, Utah is 6,121 cubic feet (173.3 m3) per second.
The Yampa River flows 250 miles (400 km) through northwestern Colorado in the United States. Rising in the Rocky Mountains, it is a tributary of the Green River and a major part of the Colorado River system. The Yampa is one of the few free-flowing rivers in the western United States, with only a few small dams and diversions.
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 Powell Geographic Expedition of 1869, led by American naturalist John Wesley Powell, was the first thorough cartographic and scientific investigation of long segments of the Green and Colorado rivers in the southwestern United States, including the first recorded passage of white men through the entirety of the Grand Canyon. The expedition, which lasted approximately three months during the summer of 1869, embarked from Green River Station, Wyoming Territory and traveled downstream through parts of the present-day states of Colorado and Utah before reaching the confluence of the Colorado and Virgin rivers in present-day Arizona and Nevada. Despite a series of hardships, including losses of boats and supplies, near-drownings, and the eventual departures of several crew members, the voyage produced the first detailed descriptions of much of the previously unexplored canyon country of the Colorado Plateau.
Brown's Park or Browns Park, originally called Brown's Hole, is an isolated mountain valley along the Green River in Moffat County, Colorado and Daggett County, Utah in the United States. The valley begins in far eastern Utah, approximately 25 miles (40 km) downstream from Flaming Gorge Dam, and follows the river downstream into Colorado, ending at the Gates of Lodore in Dinosaur National Monument. Known as a haven for outlaws such as Butch Cassidy and Tom Horn during the late 19th century and the early 20th century, it is now the location of the Browns Park National Wildlife Refuge. It was also the birthplace of Ann Bassett. She and her sister Josie Bassett, were considered female outlaws and girlfriends to several of Cassidy's Wild Bunch gang. It is the location of John Jarvie Historic Ranch, where, in 1880, Scotsman John Jarvie built a ranch along the Green River.
Flaming Gorge Dam is a concrete thin-arch dam on the Green River, a major tributary of the Colorado River, in northern Utah in the United States. Flaming Gorge Dam forms the Flaming Gorge Reservoir, which extends 91 miles (146 km) into southern Wyoming, submerging four distinct gorges of the Green River. The dam is a major component of the Colorado River Storage Project, which stores and distributes upper Colorado River Basin water.
Echo Park (Colorado) is a remote river bottom surrounded by canyon walls on the Green River, just downstream from the confluence with the Yampa River and across the stream from the dramatic southern end of Steamboat Rock in Dinosaur National Monument. It was first mapped and given its name by the Powell Geographic Expedition in 1869. A proposed dam at Echo Park turned into a nationwide environmental controversy in the early 1950s. The Sierra Club and other conservationist groups helped forge a compromise in Congress that eliminated the Echo Park Dam from the Colorado River Storage Project Act of 1956.
The Glen Canyon Group is a geologic group of formations that is spread across the U.S. states of Nevada, Utah, northern Arizona, north west New Mexico and western Colorado. It is called the Glen Canyon Sandstone in the Green River Basin of Colorado and Utah.
Gateway is an unincorporated community and a U.S. Post Office located in Mesa County, Colorado, United States. The Gateway Post Office has the ZIP Code 81522.
Toponas is an unincorporated rural village in Routt County, Colorado, United States. The community took its name from nearby Toponas Rock. The population in 2010 was 48; in 2017 it is estimated at 26, all in ages ranging from 55 years upwards.
The humpback chub is a federally protected fish that lived originally in fast waters of the Colorado River system in the United States. This species takes its name from the prominent hump between the head and dorsal fin, which is thought to direct the flow of water over the body and help maintain body position in the swift currents of the Colorado. The body is almost entirely scaleless, retaining only about 80 mid-lateral scales along the lateral line. The fish is very streamlined, with a thin caudal peduncle and a deeply forked tail. The back is a light olive gray, the sides silver, and the belly white. The dorsal fin usually has nine rays, and the anal fin 10 or more. Maximum recorded length is 38 cm.
The Dinosaur Diamond is a 486-mile (782 km) scenic and historic byway loop through the dinosaur fossil laden Uinta Basin of the U.S. states of Utah and Colorado. The byway comprises the following two National Scenic Byways:
Yampa River State Park is a Colorado state park located along the Yampa River in Routt and Moffat Counties in northwestern Colorado in the United States.
State Highway 318 (SH 318) is a state highway in Moffat County, Colorado. SH 318's western terminus is at Brown's Park Road at the Utah state line, and the eastern terminus is at U.S. Route 40 (US 40) in Maybell.
Echo Park Dam was proposed in the 1950s by the U.S. Bureau of Reclamation as a central feature of the Colorado River Storage Project. Situated on the Green River, a major tributary of the Colorado River, the dam was proposed for the Echo Park district of Dinosaur National Monument, flooding much of the Green and Yampa river valleys in the monument. The dam was bitterly opposed by preservationists, who saw the encroachment of a dam into an existing national park as another Hetch Hetchy, to be opposed as an appropriation of protected lands for development purposes. The Echo Park project was abandoned in favor of Glen Canyon Dam on the main stem of the Colorado, in lands that were not at that time protected. This was eventually regarded as a strategic mistake by conservation organizations.
Crouse Creek is a stream in the Uinta Mountains near the eastern edge of Daggett County, Utah, United States.
Steamboat Rock is a 6,074-foot (1,851-meter) elevation cape located in the 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.
