The Marsh-Billings-Rockefeller National Historical Park was established in Vermont on August 26, 1992. It’s the first national park in the country created to honor the history of conservation. The park property was first purchased in 1789 by Joseph Marsh for his 23-year-old son Charles. Charles cleared the eastern slopes of Mount Tom to create a pasture and purchased additional land to expand his farm. When Charles died in 1849, the property passed to his son Charles Jr. However, it was Charles Sr.’s son George who would have the greatest effect on the land of anyone in the Marsh family, though not directly.
