The coastal marshlands and rocky peninsulas of Cumberland County are captured in this orthophotograph, where the Dunstan River and Nonesuch River wind through the expansive salt marshes of Scarborough. This aerial perspective highlights the distinct transition between the developed residential areas of South Portland and the jagged shoreline extending toward Prouts Neck. The 1970s landscape shows the established beach communities of Higgins Beach and Blue Point before further modern expansion. By utilizing an aerial photograph from April 30, 1975, the map provides a clear view of the sediment patterns in Saco Bay and the detailed street grids of Old Orchard Beach, offering a precise record of the shoreline and maritime geography during this era.
