Prior to European contact, a band of the Massachusett Native American tribe maintained a village in what is now Cohasset. It was known as Quonahassit — often translated as “long rocky place.” In 1614, while exploring what was known then as the New World, Captain John Smith (1580-1631) landed in “Quonahassit Harbor” to trade for furs. The Quonahassit village was probably in the vicinity of today’s Elm Street, a summer camp for fishing, and for growing corn, beans and squash. The village moved inland during the winter for shelter, and to hunt for deer, turkey and other wildlife. A widespread plague decimated the Quonahassit population shortly after Smith’s visit.

To learn more about local Native American tribes, we encourage you to interact with their members. The Massachusett tribe at Ponkapoag shares information on its website.

Habitats and Wildlife

Sandy Beach is a barrier beach known for its white sand. It is located on the Atlantic coastline, overlooking Massachusetts Bay.

The Williams Salt Marsh, 4.2 acres of salt marsh and upland on Little Harbor, is located across the street. It was donated to the Cohasset Conservation Trust in 2012 by Susan Williams Dickie. An additional parcel of land was added in 2016, thanks to a donation from the Wakeman family.
