In the mountaineering parlance of the Western United States, a fourteener is a mountain peak with an elevation of at least 14,000 ft. The 96 fourteeners in the United States are all west of the Mississippi River. Colorado has 53 fourteeners, the most of any single state. Alaska has 29, the second most of any single state. Many peak baggers try to climb all fourteeners in the contiguous United States, one particular state, or another region. From Wikipedia
