1972 Map of Great Point

About this map

Nantucket Island stretches into the sea at its northernmost reaches on this 1972 survey, centered on the thin, wave-sculpted barrier of Great Point. A prominent Lighthouse stands at the tip, marking the critical junction between Nantucket Sound and the open Atlantic Ocean. The landscape is defined by the shifting sands of The Galls and the intricate wetlands around Coskata Pond. This chart captures the area's geography following updates from 1969 and 1970 aerial photography, documenting the fragile connections between the main island and landforms like Coatue and The Glades. Human presence is minimal, limited to the small settlements of Coskata and Wauwinet and a network of Jeep Trails that navigate the coastal terrain near Head of the Harbor. The detailed hydrographic data includes soundings and the vast Tidal Flat areas that characterize this dynamic maritime environment.
