Mount Clay is a broad, high shoulder on the Presidential Range ridge in New Hampshire’s White Mountains, between Mount Washington and Mount Jefferson. Rising to 5,533 feet but only modestly above the surrounding ridge, it is closely associated with the heavily traveled trail network near Mount Washington, including the Appalachian and Gulfside trails and the Mount Clay Loop. Named for Henry Clay, it was designated Mount Reagan in New Hampshire law in 2003, but that change remained limited after the U.S. Board on Geographic Names declined to adopt it in 2010, and foot-travel maps continued to use Mount Clay. Though above 4,000 feet, it is treated as a secondary summit rather than a separate four-thousand-footer.
