What is now Nauset Marsh was once a freshwater system until the shoreline in the area eroded, connecting the landscape to the sea. When the area was mapped by French explorer Champlain in 1605, it was a navigable bay. Over the years, ocean currents deposited a narrow strip of sand along the outer shore, now known as Nauset Spit. The spit acts as a barrier to the Atlantic Ocean and allowed the extensive marsh landscape to develop. https://npshistory.com/publications/caco/guides-guide/salt-pond-nauset-marsh.pdf

The Salt Pond is a twelve-meter-deep tidal pool that flows into the Atlantic Ocean. The lake was formed about 18,000 years ago when glaciers retreated and left depressions. The Salt Pond was originally a freshwater lake and became a saltwater lake that is subject to the tides. A narrow channel connects the lake to the Nauset Marsh on the Atlantic Ocean. The Salt Pond continues to change; the connecting channel to the marsh is gradually filling with sand. https://npshistory.com/publications/caco/guides-guide/salt-pond-nauset-marsh.pdf
