Boulderwood is a historic private summer camp on the shore of Squam Lake in Holderness, New Hampshire. Located on Mooney Point, the camp was developed beginning in the 1920s by Elwyn G. Preston. Preston, whose family had summered in other camps located on the point, began purchasing land in 1922, which included 2,000 feet (610 m) of shoreline, which was gradually expanded with other land purchases.[2]
