USGS Topo · Published 1960

About this map

Coastal defenses and maritime infrastructure define this mid-century survey of the Maine shoreline. Significant military installations including Fort Williams Military Res, Fort McKinley Naval Res, and several harbor batteries like Fort Gorges and Fort Scammel dominate the islands and headlands protecting Portland Harbor. The map captures a high degree of institutional detail, from the Maine School for the Deaf on Mackworth Island to the Maine Vocational Technical Institute in South Portland.
