Premise: Mount Pierce is a mountain in the Presidential Range in the White Mountains of New Hampshire that is approximately 4,310 feet (1,314 m) high. Formerly called Mount Clinton for 19th-century governor DeWitt Clinton of New York, in 1913 it was renamed after President Franklin Pierce (1804–69), the only president born in New Hampshire, although the newer name is not universally accepted.
Hypothesis: The mountain was renamed over a century ago.
