Crowell Conservation Area, also known as Crowell Bog, is a retired cranberry bog with approximately 2 miles of trails. Around the former-bog areas, the trails are wide and feature views of marshes, ponds, and wetlands. A 1-mile spur trail extends south through the property to Lincoln Street. Excellent birding! 

This property was an active cranberry bog for many years. It has been retired and is slowly transitioning back to a natural state. There are still several outbuildings from the cranberry days on the property, including a large barn and two pump houses. Less picturesque is an electrical power supply, immediately adjacent.

Prior to European contact, the Mattakeeset band of the Massachuseuk (or Massachusett) Native American tribe lived for thousands of years in the North River watershed. Their village included most of today’s Pembroke and Hanson as well as parts of Duxbury. Meanwhile, the Patuxet band of the Wampanoag tribe inhabited the Jones River watershed, and the area now known as Kingston, Plymouth, and Duxbury. This property lies within the upper portion of the Green Harbor River watershed, right between those two territories. It’s possible that both tribes utilized the area.

Approx. 1 mile of trails around former bogs. Trails are wide and flat, occasionally thick with grass and vines, but mostly clear. There are some wet/muddy sections. From the southeastern portion of the loop, look for a 1-mile spur trail that leads into the woods, and loops around to Lincoln Street.

Retired cranberry bogs now transitioning into wetlands and marsh. Mostly open space with some pine, oak, hemlock, and birch trees. Watch for red-winged blackbirds in the marsh areas. There are two small ponds on the property as well. This property is among the headwaters of the Green Harbor River, which flows from Duxbury into Marshfield, and out to sea at Green Harbor.
