The Gem States capital is located in Boise, and the state has a land area of 83,574 square miles. Idaho's highest point is located at Borah Peak at 12, 662 feet and its lowest point is the Snake River at 710 feet. Part of the Eastern boundary of Idaho is formed by the Continental Divide (the crest of the Rocky Mts.). The Snake River forms part of the Western boundary of the state. Idaho has traditionally been known for its agricultural, forest, and mineral resources. By the 1990s, however, services and manufacturing had supplanted agriculture as the state's leading economic sectors. Tourism is increasingly important to the economy; many visitors are lured to Idaho each year by the unspoiled beauty of the mountain wilderness areas. The name of the state is derived from an Indian word that may be a Kiowa Apache name for the Comanche. Idaho's nickname is the Gem State.
