In the Rocky Mountains there is a large number of four-thousanders, especially in the state of Colorado (Mount Elbert: 4,402 m) and Wyoming (Gannett Peak: 4,210 m). In addition the Sierra Nevada rises well above 4,000 m; its highest peak is Mount Whitney at 4,420 m. On Hawaii the volcano of Mauna Kea lies 4,214 m above sea level and has an overall height of 9,705 m above the seabed. The US-American equivalent of the four-thousanders are the fourteeners, which include all mountains that are higher than 14,000 feet (4,267.2 m).
