The Pemigewasset River valley serves as the primary corridor for settlement and transportation in this 1980s-era study, where the communities of Woodstock, West Thornton, and Thornton are clustered along the riverbanks. The landscape is dominated by the heavily wooded peaks of the White Mountain National Forest, including Mount Cilley and Barron Mtn, which restrict development to the narrow lowlands. This geography dictated a linear infrastructure pattern, with modern interchanges like Interchange 31 following the same valley floor that supported earlier civic life at the Thornton Ch and Thornton Sch.
