The area around Fort Hill was reclaimed by the Pilgrim settlers after 1644 and used for agriculture until the 1940s. The forest was cleared and the wetlands drained. Dairy farming was carried out on the meadows. The settlers extracted salt from the beach using a complex process. Today the areas are a protected area, the wetlands have been reclaimed in a natural state and can be experienced, for example, on a walk on the Fort Hill Trail. https://www.nps.gov/caco/learn/historyculture/fort-hill.htm
