Old Clump Mountain, a Catskills summit in New York spanning the towns of Stamford and Roxbury, rises to 2,926 feet and is significant for its strong connection to writer and naturalist John Burroughs. Beyond its mountain setting, it is the site of a registered National Historic Landmark preserving Burroughs's birthplace, his boyhood and summer homes, and his burial site. This close association ties the landscape directly to the life and memory of one of America's best-known nature writers, giving the mountain historical and cultural importance as well as natural distinction.
