About this map

The Weweantic River and Wareham River converge near this coastal landscape of protected coves and narrow necks, where 21st-century settlement patterns reflect a long history of maritime life and seasonal recreation. Dense residential enclaves like Swifts Beach, Hamilton Beach, and Parkwood Beach occupy the finger-like peninsulas, while the village of Onset and Point Independence frame the head of Onset Bay.

Maritime hazards and navigation routes are prominent, from the shallow reaches of Broad Marsh River to the open waters surrounding Wickets Island and Onset Island. Inland, the map documents cultural landmarks such as the Agawam Cem and the rise of Bourne Hill. This topography captures the transition from the bustling harbors at Barlows Landing and Pocasset to the quieter shoreline of Sippican Neck, illustrating how the intricate coastline of Buzzards Bay shaped the development of these communities.
