Carrabassett River and Kennebec River converge in this orthophotoquad, illustrating the hydraulic geography of Somerset County in the mid-1970s. The aerial imagery highlights the concentration of development along the eastern riverbanks, where North Anson, Anson, and Madison form a chain of riverfront settlements. Beyond the populated corridors, the landscape transitions into a vast expanse of timberland and agriculture, broken only by rural intersections like Five Corners. This orthophotograph, prepared by the Geological Survey from 1976 aerial photography, provides a rare visual record of land use and forest cover before decades of modern growth. Researchers can trace the path of Sandy Brook as it winds through the southern reaches, providing a clear view of the natural drainage patterns that shaped the region's early rural development.
