Fourteener
In the mountaineering parlance of the Western United States, a fourteener is a mountain peak with an elevation of at least . The 96 fourteeners in the United States are all west of the Mississippi River. Colorado has the most (53) of any single state; Alaska is second with 29. Many peak baggers try to climb all fourteeners in the contiguous United States, one particular state, or another region. Qualification criteria. The summit of a mountain or hill may be measured in three principal ways: Not all summits over 14,000 feet qualify as fourteeners. Summits that qualify are those considered  by mountaineers to be independent. Objective standards for independence include topographic prominence and isolation (distance from a higher summit), or a combination of the two. However, fourteener lists do not always use such objective rules consistently. A rule commonly used by mountaineers in the contiguous United States is that a peak must have at least of prominence to qualify. By this rule, Colorado has 53 fourteeners, California has 12, and Washington has two. According to the Mountaineering Club of Alaska, the standard in Alaska uses a prominence rule rather than a rule. By this rule, Alaska has at least 21  peaks over and its 12 highest peaks exceed . Fourteeners. The following table lists the 96 mountain peaks of the United States with at least of topographic elevation and at least of topographic prominence]. Of these, 53 rise in Colorado, 29 in Alaska, 12 in California, and one in Washington (Liberty Cap is part of the crater atop Mt Rainier). The 22 highest fourteeners all rise in Alaska. Topographic prominence. The table above uses a minimum topographic prominence criterion of and includes 97 peaks. The number of peaks included depends upon the minimum topographic prominence criterion. A criterion of includes 90  peaks, includes 77 peaks, includes 63 peaks, and includes 46 peaks. The following U.S. summits have 14,000 ft of elevation, but have less than 300 ft of topographic prominence:
