The Presidential Range is a mountain range located in the White Mountains of the U.S. state of New Hampshire. It contains the highest peaks of the Whites, the most notable of which are named for American presidents, followed by prominent public figures of the 18th and 19th centuries. The Presidential Range is notorious for having some of the worst weather on Earth, mainly because of the unpredictability of high wind speeds and whiteout conditions on the higher summits. Because of the poor weather conditions, the Presidential Range is often used for mountaineering training for those who go on to climb some of the world's highest mountains, including K2 and Everest.
