Selden Island, River island in Montgomery County, Maryland.
Selden Island is a river island in the Potomac River between Maryland and Virginia. The land features mixed forests, open meadows, and natural habitats that support diverse wildlife and plant communities.
People settled on this island around 3000 years ago, leaving behind pottery and other artifacts. Later archaeologists found evidence of an established village with distinctive pottery styles that these early inhabitants developed.
The Walker Prehistoric Village on Selden Island received recognition through its inclusion in the National Register of Historic Places in 1975.
The island is reachable by a bridge connecting to the mainland, allowing visitors to arrive by foot. The best time to explore is during warmer months when the trails are easy to walk and wildlife is active.
Today the island is part of a research campus that has attracted scientists since the early 2000s. This blend of ancient settlement remains and contemporary research facilities makes the place where past and present meet in an unexpected way.
