Idaho is a state in the Pacific Northwest of the United States. The state's capital and largest city is Boise. Residents are called "Idahoans." Idaho was admitted to the Union on July 3, 1890, as the 43rd state.

According to the United States Census Bureau, in 2004, Idaho had an estimated population of 1,393,262. The state's postal abbreviation is ID. Idaho is nicknamed the Gem State because of its abundance of natural resources. The state motto is Esto Perpetua (Latin for "Let it be perpetual").

Southern Idaho, including the Boise metropolitan area, Idaho Falls, Pocatello, and Twin Falls are in the Mountain Time Zone. Areas north of the Salmon River, including Coeur d'Alene, Moscow, and Lewiston, are in the Pacific Time Zone.

Idaho borders the states of Washington, Oregon, Nevada, Utah, Montana, Wyoming and the Canadian province of British Columbia (the Idaho-BC border is 48 miles (77 km) long). The landscape is rugged with some of the largest unspoiled natural areas in the United States. It is a Rocky Mountain state with abundant natural resources and scenic areas. The state has snow-capped mountain ranges, rapids, placid lakes and steep canyons. The waters of Snake River rush through Hells Canyon, deeper than the Grand Canyon. Shoshone Falls plunges down rugged cliffs from a height greater than that of Niagara Falls.

The major rivers in Idaho are the Snake River, the Clearwater River and the Salmon River. Other significant rivers include the Boise River and the Payette River.

Idaho's highest point (12,662 feet, 3,862 m) is Borah Peak in the Lost River Mountains north of Mackay. Idaho's lowest point is in Lewiston, where the Clearwater River joins the Snake River and continues into Washington.
