Wilderness Landscape & Natural Heritage
The Green River begins in the Wind River Mountains of Wyoming, flowing south through Wyoming and Utah until it merges with the Colorado River in Canyonlands National Park. Its total length is about 730 miles. The river is known for its dramatic canyons, carved deep by the erosive power of water over millions of years. Particularly notable are the Desolation and Grey canyons, which are popular for white-water rafting. The Green River corridor hosts a diverse ecosystem, from lush vegetation along its banks to the desert landscapes further away. Wildlife is abundant, with sightings of pronghorn antelope, mule deer, and a variety of bird species being common. The river holds historical significance as it was a route used by many explorers and Native American tribes. It now plays a critical role in local economies through tourism, agriculture, and its role in regional hydrology.
