Maps of Idaho

Physical Map of Idaho. It shows the physical features of Idaho including its mountain ranges and major rivers.

Covering an area of 216,443 sq. km, the State of Idaho is located in the Pacific Northwest region of the United States.

As observed on the map, Idaho is covered from north to south by the Rocky Mountains and contains several individual mountain ranges. The most significant ones include the Bitterroots which stretch along much of its border with Montana, and the Caribou, Clearwater, Owyhee, Sawtooth, and Seven Devils ranges. Located in the Lost River Range, in eastern Custer County is the Borah Peak – the state’s highest point, at an elevation of 12,662ft (3,859m).

The Continental Divide is an imaginary line that indicates the absolute highest points of land, where on either side, some of the rivers will flow downhill or in east or west. This dividing line runs from northwestern Canada to the south along the crests of the Bitterroot Range of the Rocky Mountains in Idaho, and then to the south into Mexico, where it follows the peaks of the Sierra Madre Occidental.

Idaho’s most significant river is the Snake River, which rises in the Grand Tetons of Wyoming and flows to the Columbia River in Washington State. Other rivers of note include the Clearwater, Bear, Bruneau, Kootenai, and Salmon River. Along with these main rivers, about 16,000 miles of smaller rivers and streams also drains the state’s land. The major lakes of the state include the Coeur d'Alene and Pend Oreille. Situated at a point near Lewiston, where the Snake River joins the Clearwater River, is the state’s lowest point, at an elevation of 710ft (216m).

Running through the south-central part of the state, the Snake River Plain is a wide, fertile plain and a flat lava-based, bow-shaped depression, which is also home to the state's agricultural industries. The waters of the Snake River dissect the Hells Canyon - the deepest gorge in America, located on the Idaho-Oregon border, at a maximum depth of 7,993ft (2,463m). The Shoshone Falls located along the Snake River near the Twin Falls, in the southern part of the state stands at 212 ft. high, which is about 45ft higher than the Niagara Falls.

The “Craters of the Moon National Monument” spans over 750,000 acres in southern Idaho, and is in essence, a sea of young lava flows, complete with scattered islands of cinder cones and sagebrush.
