Escalante River
The Escalante River is a tributary of the Colorado River, approximately 90 mi (145 km) long, in southern Utah. Its headwaters are on the high forested slopes of the Aquarius Plateau. It drains a remote area west of the Colorado, flowing through rugged canyons for much of its route.
It rises in several creeks along Hell's Backbone in western Garfield County, approximately 20 mi (32 km) west of the town of Escalante in the Dixie National Forest. It flows east to Escalante, entering Grand Staircase-Escalante National Monument and flowing through the Escalanate Canyons, a series of narrow spectacular gorges. It turns southeast in central Garfield County, entering Glen Canyon National Recreation Area and entering the Colorado from the northwest as an arm of Lake Powell, approximately 20 mi (32 km) north of the Arizona state line.
