2021 Map of Great Point

About this map

The Galls stands as the primary topographical feature on this coastal survey conducted by the U.S. Geological Survey. This specific environment illustrates the dynamic and shifting nature of the Massachusetts coastline, where narrow strips of land are subject to the constant influence of the Atlantic. The 2021 data reflects the contemporary state of these barrier features, which serve as critical landmarks for local navigation and coastal monitoring. Because this quadrangle is predominantly composed of open water, it provides a precise baseline for researchers studying littoral drift and shoreline migration along this isolated stretch of the shore.
