Idaho is one of the Mountain states of the US. It is an entirely landlocked state, sharing its boundaries with Oregon, Washington, Utah, Nevada, Montana, Wyoming, and the state of British Columbia in Canada. The name "Idaho" was used for a steamship which traveled the Columbia River. "Idaho" is a coined or invented word, and is not a derivation of an Indian phrase "E Dah Hoe (How)" supposedly meaning "gem of the mountains."

Idaho is 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 1990s saw a remarkable growth in the high technology industries, concentrated in the metropolitan Boise area.

With the growth of winter sports, tourism now outranks other industries in revenue. Idaho's many streams and lakes provide fishing, camping, and boating sites. The nation's largest elk herds draw hunters from all over the world, and the famed Sun Valley resort attracts thousands of visitors to its swimming, golfing, and skiing facilities.
