Gilmanton Ironworks serves as the focal point of this Belknap County landscape, situated where the Suncook River flows south from Sunset Lake. The area's complex topography is defined by the Belknap Mountains in the northwest and a series of prominent heights including Cogswell Mtn and Rocky Mtn. This modern survey details a region characterized by numerous glacial lakes and ponds, from the clusters of Manning Lake and Lake Eileen to the larger basins of Upper Suncook Lake and Lower Suncook Lake. Local genealogy and historical settlement patterns are preserved through several burial grounds, such as the Smith Meeting House Cem near Lower Gilmanton and the Pickering Lot Cem. The network of backroads, including Places Mill Rd and Guinea Ridge Rd, traces the historic routes between these highland communities and their water-powered industry sites.
