14 mapped spots across 12 counties. Mississippi produces a wide range of rockhounding-grade material: see the full list of spots, minerals, and access notes below.
The best rockhounding in Mississippi is at Gulfport in Harrison County (jasper, petrified wood), Twentymile Creek in Prentiss County (fossil, petrified wood), and Wesson in Copiah County (banded agate, chalcedony). In total, 14 mapped collecting spots across 12 counties produce petrified wood, agate, and fossil, each listed below with coordinates and land access notes.
Representative spot and material photos from locations in this state, shown where verified public image records are available.

Counts reflect how many spots in this list mention each mineral.
Day-trip range. Each section lists the closest mapped rockhounding spots within about 150 miles of the city. Most are inside a 2 to 3 hour drive.

Geology rarely respects state borders. These states share mapped rockhounding country with Mississippi, useful when Mississippi is the start, not the whole trip. Each card links to the closest county across the line.
County pages are linked once we have at least 3 mapped spots for a focused guide with coordinates, mineral notes, and nearby spots.
Hand-picked standouts from the Mississippi list, chosen for unusual mineralogy, documented public access, or both. Each card links to coordinates, access notes, and what to look for.
Top pickHarrison County
Harrison County's Pliocene and Pleistocene Citronelle Formation and terrace gravels carry jasper, agate, chert, and petrified wood pebbles across the coastal plain behind Gulfport.
Jasper, Petrified Wood
Top pickPrentiss County
Twenty Mile Creek near Baldwyn cuts through the Campanian Demopolis Formation and the underlying Coffee Sand, exposing a marine fossil bed roughly 75 million years old.
Fossil, Petrified Wood
Top pickCopiah County
The upland terrace and Citronelle gravels around Wesson in Copiah County produce banded agate, chalcedony, and petrified wood, all catalogued from the county on mindat.
Banded Agate, Chalcedony, Petrified Wood
Top pickItawamba County
The Tombigbee River in Itawamba County flows past Cretaceous chalk and sand of the Coffee Sand, Demopolis, and Prairie Bluff units, the same fossil-bearing belt exposed farther south.
Shark Tooth
Top pickTishomingo County
The clay and lignite beds around Paden in Tishomingo County are one of the few documented sources of Upper Cretaceous amber in Mississippi, tied to the Coffee Sand and Tuscaloosa Group.
Amber
Top pickWayne County
Creek gravels around Waynesboro in Wayne County carry petrified palm wood and silicified wood eroded from Citronelle and Hattiesburg-age sediments of southeast Mississippi.
Fossil, Petrified Palm Wood
Top pickTunica County
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.
Agate, Fossil
Top pickMarshall County
Holly Springs National Forest sits on Eocene Wilcox and Claiborne sands and reworked upland gravels that carry silicified and petrified wood, Mississippi's official state stone.
Petrified Wood
Top pickAdams County
Adams County in the far southwest yields banded agate, quartz, and chalcedony from Citronelle and Mississippi River terrace gravels, historically collected from commercial gravel stockpiles along the Natchez riverfront.
Banded Agate
Top pickScott County
Bienville National Forest spreads across central Mississippi on Oligocene and Miocene sediments that host the state's petrified wood, formed when buried hardwood was replaced grain by grain with chalcedony and opal.
