1968 Map of Mathias Point

About this map

Cedar Point Neck dominates this landscape, a prominent peninsula defined by the convergence of the Potomac River, Nanjemoy Creek, and the Port Tobacco River. During the late 1960s, this area of Charles County served as a significant site for federal research and defense, housing the U S Naval Research Laboratory and Harry Diamond Laboratories. The interior reflects a rural social fabric with small settlements such as Mcconchie, Welcome, and Hill Top, alongside spiritual centers like Zion Ch and The Welcome Mission. The map's bathymetric data reveals the complex underwater contours of the riverbeds, particularly around Upper Cedar Pt and Blossom Pt, where the deep channel of the Potomac creates a sharp contrast with the shallow coves of Gumtree Cove and Goose Creek.
