National Seashores, Lakeshores, and Rivers

National Seashores, Lakeshores, and Rivers

National seashores, lakeshores, and rivers preserve coastal and freshwater environments shaped by the interaction of water, climate, and geologic processes across a range of geographic settings. These landscapes often include barrier islands, rocky shorelines, sand dunes, river corridors, and freshwater coastlines that illustrate long-term patterns of erosion, sediment transport, and ecological succession. Marine and freshwater environments support diverse plant and animal communities adapted to changing water levels, seasonal climate variation, and coastal weather patterns.

Atlantic and Pacific coastal environments preserved within Cape Cod National Seashore, Fire Island National Seashore, Gulf Islands National Seashore, and Point Reyes National Seashore demonstrate the dynamic nature of coastal landscapes shaped by tides, wind, and ocean currents. Barrier island systems and coastal headlands illustrate the ongoing interaction between marine environments and continental landforms.

Freshwater coastlines preserved within Apostle Islands National Lakeshore and Pictured Rocks National Lakeshore demonstrate the geological influence of glaciation across the Great Lakes region. Sandstone cliffs, sea caves, beaches, and forested shorelines reflect the interaction between freshwater wave action and sedimentary rock formations shaped during the last Ice Age.

River corridors and coastal environments together illustrate the importance of waterways as ecological systems, transportation routes, and settings for human settlement. Through preservation of shorelines, estuaries, dunes, wetlands, and coastal forests, national seashores, lakeshores, and rivers protect landscapes that reflect the continuous interaction between land and water across both marine and inland environments.
