Mississippi River: Fossil Hunting in Tunica County, Mississippi
Updated July 2026
Point-bar gravels along the Mississippi River in Tunica County carry quartz, chalcedony, agate, chert, and petrified wood rafted downstream from as far as the Great Lakes and the Ozarks. The mix makes the Delta shoreline one of the few places in flat northwest Mississippi to find hard, colorful lapidary material. Productive gravel is patchy but concentrates on exposed bars at low water. Reported finds include agate, fossil. Below: coordinates, access notes, nearby spots, and trip-planning links.
