Green River: I 80 - Tunnel West - West
The Green River defines the setting of Green River — its broad valley cuts through Wyoming’s high desert, bringing a ribbon of riparian land to sagebrush country. In Sweetwater County, the community developed as a Union Pacific railroad town after the line reached the river in 1868. Interstate 80 and the railroad now follow the same east–west corridor, while open basins, pale rock formations and low buttes characterize the surrounding terrain. The Green River is the Colorado River’s largest tributary and continues south through canyon country. River, rail and highway connections give Green River a practical, wide-open identity in southwestern Wyoming.

Among Wyoming’s cities, Green River stands out as the launching point of John Wesley Powell’s 1869 expedition down the Green and Colorado rivers. Set beside the Green River in southwestern Wyoming, the city developed as a Union Pacific railroad town and remains the seat of Sweetwater County. Its high-desert setting is shaped by open sagebrush country, broad skies and the river corridor, while Expedition Island recalls the party’s departure toward the canyons of the Colorado Plateau. Railroad heritage and riverfront parks give Green River a practical western character.

Wyoming stretches from the Montana border to its frontiers with Colorado and Utah, encompassing the high Rockies, broad basins, and Great Plains. The Continental Divide crosses the state, while the Wind River and Bighorn River drain contrasting sides of its interior. In the northwest, Yellowstone National Park—established in 1872 as the world’s first national park—and Grand Teton National Park place geothermal country and sharp mountain relief at the centre of Wyoming’s identity. Ranching remains integral to its open-country culture, alongside communities shaped by railroads, energy, and outdoor travel.

The Atlantic, Pacific and Gulf coasts define much of the United States — their ports, fisheries and trade routes have long tied the country’s economy to the wider world. Between them, the Rocky Mountains, Great Plains and Mississippi River basin form sharply different regions, from high western ranges to broad agricultural heartlands. Cities carry much of the national story: New York’s Statue of Liberty, a gift from France dedicated in 1886, remains an enduring symbol, while Washington, DC concentrates major federal institutions. Indigenous nations have shaped these lands for millennia, and their living cultures remain essential to the country’s identity.
