Prospect Hill marks the prominent terrain of this remote northern borderland where the United States meets Canada in Coos County. The landscape is defined by its international boundary and a network of drainage basins flowing northward into Quebec. This survey documents the headwaters of several significant regional watercourses, including Rivière Ditton Ouest, Rivière Ditton Est, and Rivière Chesham.
