Nauset Marsh Trail Footbridge Temporary Closure After Labor Day
A small footbridge on the Nauset Marsh trail will be closed for repair for two weeks following Labor Day. Ask at the visitor center for detour information.
Sections of Boardwalk Closed at Red Maple Swamp Trail
Sections of the boardwalk at the Red Maple Swamp Trail have been closed due to structural deterioration and safety concerns. Check at Salt Pond Visitor Center for the current status of this trail, and for your safety, remain out of closed areas.
It is difficult to overstate the importance of water as a resource. Amplifying the importance of water on Cape Cod is the fact that the fresh water supply comes solely from an underground aquifer system that is recharged almost exclusively through precipitation. With this in mind, the Cape Cod National Seashore, in collaboration with the United States Geological Survey, has developed a standardized, long-term methodology of monitoring hydrological activity on the Outer Cape.
The freshwater aquifer of the Outer Cape is bound laterally and below by salt water and is divided into four distinct flow "lenses." These flow lenses are detailed in the map below. Coastal hydrological processes are also of great interest, especially as they relate to salt marsh restoration projects throughout the Seashore.
Climate change, sea-level rise, and increased withdrawal rates from groundwater all have the potential to significantly impact the fresh water resources critical to the human population and the sensitive coastal ecosystems of the Outer Cape. The Seashore's long-term hydrological monitoring program will provide a better understanding of the effects of both natural and human-induced change on groundwater levels of the Cape Cod aquifer.

In 1990, an intense series of storms uncovered a prehistoric site on Coast Guard Beach in Eastham, MA. Archaeologists excavated the Carns Site, which was lived in by native peoples during the Early and Middle Woodland period, or approximately 2,100 to 1,100 years ago.
