The Virgin River is a tributary of the Colorado River located in the southwestern United States, flowing through the states of Utah, Nevada, and Arizona. It originates in southwestern Utah at the Navajo Reservoir in the Dixie National Forest, north of Zion National Park. The river is formed by the confluence of the East Fork Virgin River and the North Fork Virgin River, which flows through Zion Canyon in Zion National Park. From there, it flows southwest, passing south of St. George, Utah, then through northwestern Arizona via the Virgin River Gorge, and finally enters southern Nevada near Mesquite before emptying into the Colorado River at Lake Mead, about 40 miles east of Las Vegas. The river is approximately 162 miles (261 km) long

. In summary, the Virgin River runs through Utah, Arizona, and Nevada, starting in Utah and ending in Nevada at Lake Mead, a reservoir on the Colorado River
