Blackwater River and the Merrimack River converge in this region of Merrimack County, shaping a landscape defined by historic mill sites and water management. The legacy of early industry is visible at Snyders Mill and Swetts Mills, while the later infrastructure of the Blackwater Dam stands north of Lake Winnepocket. Small crossroads settlements like Dingit Corner, Gerrish Corner, and Davisville are connected by a network of roads traversing named heights such as Corser Hill and Putney Hill. Further east, the river corridor supports the Merrimack River State Forest and the State Forest Nursery, alongside unique mid-century landmarks like a Drive-In Theater near Boscawen. The southern portion of the map transitions into the corporate boundaries of Concord, showing the development around Mast Yard near the Contoocook River.
