A Freshwater Oasis
The following is transcribed from one of the many informational signs/plaques that are found throughout the Assteague Islannd National Seashore:
Naturally occurring freshwater ponds are scattered through Assateague’s forest zone. They usually form shallow depressions between old dunes or in low areas that extend below the water table. There exposed freshwater pockets float on top of heavier salt water and are replenished by rainfall.
Protected from harsh winds by the thick vegetation, ponds provide shelter and essential drinking water for many island dwellers.
