Idaho is one of the Rocky Mountains states of the United States of America. Idaho is a rugged state, with 10,000 - 12,500 ft (3000 - 3800m) snow-capped mountains, whitewater rivers (one running through the deepest river canyon in the U.S.), forests, high desert, and plenty of wilderness. Most of the land north of Boise is National or State Forest. Read more from Wikitravel »
