Douglas Point — Rockhounding in Charles County, Maryland
Updated July 2026
Douglas Point is one of the few Bureau of Land Management recreation areas in the eastern United States, protecting about 1,270 acres of Potomac River shoreline jointly managed with the State of Maryland. Its beaches expose the same Paleocene Aquia Formation as nearby Purse State Park and yield fossil shark teeth and ray plates. The BLM's own visitor materials describe the shoreline as a fossil-bearing beach. Reported finds include shark teeth, fossils. Below: coordinates, access notes, nearby spots, and trip-planning links.
