Tongue River (Montana) River in Wyoming and Montana, United States

The Tongue River is a tributary of the Yellowstone River, approximately 265 mi (426 km) long, in the U.S. states of Wyoming and Montana. The Tongue rises in Wyoming in the Big Horn Mountains, flows generally northeast through northern Wyoming and southeastern Montana, and empties into the Yellowstone River at Miles City, Montana. Most of the course of the river is through the beautiful and varied landscapes of eastern Montana, including the Tongue River Canyon, the Tongue River breaks, the pine hills of southern Montana, and the buttes and grasslands that were formerly the home of vast migratory herds of American bison.

Bighorn River

The Bighorn River is a tributary of the Yellowstone, approximately 461 miles (742 km) long, in the states of Wyoming and Montana in the western United States. The river was named in 1805 by fur trader François Larocque for the bighorn sheep he saw along its banks as he explored the Yellowstone.

Bighorn Mountains Mountain range in Wyoming and Montana, United States

The Bighorn Mountains are a mountain range in northern Wyoming and southern Montana in the United States, forming a northwest-trending spur from the Rocky Mountains extending approximately 200 miles (320 km) northward on the Great Plains. They are separated from the Absaroka Range, which lie on the main branch of the Rockies to the west, by the Bighorn Basin. Much of the land is contained within the Bighorn National Forest.

Wind River Range

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.

Wind River Indian Reservation Indian reservation in the United States

The Wind River Indian Reservation is located in the west-central portion of the U.S. state of Wyoming, where Eastern Shoshone and Northern Arapaho Native American tribes currently live. Stretching roughly 60 mi (97 km) east to west and 50 mi (80 km) north to south, the Indian reservation is located in the Wind River Basin, and includes portions of the Wind River Range, Owl Creek Mountains, and Absaroka Range.

Popo Agie Wilderness

Popo Agie Wilderness is located within Shoshone National Forest, Wyoming, United States. The wilderness consists of 101,870 acres on the east side of the continental divide in the Wind River Range. Originally set aside as a primitive area in 1932, in 1984 the Wyoming Wilderness Act was passed securing a more permanent protection status for the wilderness. The wilderness is a part of the 20,000,000 acres Greater Yellowstone Ecosystem.

Chugwater Formation

The Chugwater Formation is a mapped bedrock unit consisting primarily of red sandstone, in the states of Wyoming, Montana, and Colorado in the United States. It is recognized as a geologic formation in Colorado and Montana, but as a Group in Wyoming.

Interstate 25 (I-25) is a part of the Interstate Highway System that runs from Las Cruces, New Mexico, to Buffalo, Wyoming. In Wyoming, the Interstate Highway runs 300.530 miles (483.656 km) from the Colorado state line near Cheyenne north to its national terminus at I-90 near Buffalo. I-25 connects Wyoming's largest city and capital, Cheyenne, with its second largest city, Casper, and the smaller communities of Wheatland, Douglas, and Buffalo. The highway also connects those cities with Denver and Billings via I-90. I-25 runs concurrently with U.S. Route 87 for almost its entire course in Wyoming. The highway also has extensive concurrencies with US 20 and US 26 along its east–west segment through the North Platte River valley. The Interstate has business loops through Cheyenne, Chugwater, Wheatland, Douglas, Glenrock, Casper, and Buffalo.

Bridger Trail United States historic place

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.

Red Canyon (Fremont County, Wyoming)

Red Canyon is a canyon located in Fremont County, Wyoming in the United States of America. The uplift of the nearby Wind River Range 60 million years ago exposed sedimentary rocks that were eroded by streams. The canyon exposes a number of geologic formations including the Phosphoria Formation from the Permian Period and the Chugwater Formation from the Triassic Period. Oxidized iron deposits in the rocks give the canyon its name. Red Canyon Creek drains the canyon and feeds into the Little Popo Agie River at the northern end. The streams provide habitat for wildlife in an otherwise arid region.


The Tukudeka or Mountain Sheepeaters are a band of Shoshone within the Eastern Shoshone and the Northern Shoshone. Before the reservation era, they traditionally lived in the central Sawtooth Range of Idaho and the mountains of what is now northwest Wyoming. Bands were very fluid and nomadic, and they often interacted with and intermarried other bands of Shoshone. Today the Tukudeka are enrolled in the federally recognized tribe, the Shoshone-Bannock Tribes of the Fort Hall Reservation of Idaho and the Eastern Shoshone of the Wind River Indian Reservation in Wyoming.

The river is part of the Popo Agie Watershed and from its headwaters in the Wind River Range until it joins with the North Fork of the Popo Agie River, the river and its tributaries irrigate roughly 11,503 acres.
