Snake River Plain
From Biocrawler, the free encyclopedia.
The Snake River Plain is a geological feature of (primarily) the American state of Idaho. It stretches 400 miles (650 km) westward from northwest of the state of Wyoming to the Idaho-Oregon border. The plain is a wide flat bow-shaped depression, and covers about a quarter of Idaho. Three major buttes dot the plain east of Arco, the largest being Big Southern Butte.
The Snake River Plain traces the path of a geologic hot spot now centered in Yellowstone National Park. Volcanos that once covered the hot spot formed the Island Park, Craters of the Moon National Monument and Yellowstone Calderas.
Many of Idaho's major cities are in the Snake River Plain. Also much of its agricultural land lies there.
Also located within Snake River Plain is the Idaho National Engineering and Environmental Laboratory.
