2014 Map of Johns Island

About this map

Johns Island and the surrounding archipelagos of the Atlantic Ocean define this maritime landscape along the jurisdictional boundary of Knox and Hancock counties. The geography is characterized by numerous small islands and hazardous marine features, including several named ledges and rocks that have long been critical to local navigation. Notable among these are Sally Prude Ledge, Mason Ledge, and the submerged Johns Island Sunken Ledge. On the larger landmasses, distinctive coastal features such as Devils Head on Marshall Island and Gooseberry Point mark the interface between the rocky Maine coast and the sea. The map details a complex network of island clusters, from Brimstone Island in the west to the outer reaches of Beach Ledge, illustrating the sparse but named terrain of this remote coastal area.
