Green River Colorado & Utah

Green River -Major John Wesley Powell first explored this river in 1869 and named its most exciting rapids Disaster Falls, Triplet Falls and Hells Half Mile.

The Green River is a tributary of the Colorado River, 730 mi (1,175 km) long, in the western United States. The Green River Basin covers parts of Wyoming, Utah, and Colorado. The river begins in the Wind River Mountains of Wyoming, and flows through Utah for much of its course, draining the northeastern portion of the state while looping for 40 mi (64 km) into western Colorado. Much of its route is through the Colorado Plateau, some of the most spectacular canyons in the United States. It is the largest tributary of the Colorado, with a mean discharge of 10,150 cfs.

South of the Flaming Gorge Dam in northeastern Utah the Green River flows eastward, looping around the eastern tip of the Uinta Mountains going from Utah into northwestern Colorado, then south into Dinosaur National Monument where it passes through the Canyon of the Lodore (Otherwise known as the Gates of Lodore) and is joined by the Yampa River at Steamboat Rock. It turns westward back into Utah along the southern edge of the Uintas in Whirlpool Canyon.

The Green River flows through Split Mountain Canyon before leaving Dinosaur National Monument in a meandering path across a broad irrigated flood plain.
