Girard

Girard is a small Burke County town on the Savannah River, and its name is attached to one of the Southeast's better-known regional rockhounding materials: Savannah River agate, sometimes called Georgia chert. It's not a true agate in the strict mineralogical sense — collectors and geologists describe it as a mixed conglomeration of agate, jasper, chert, and opalite, likely weathered out of Oligocene-age (30–35 million-year-old) Jackson Group, Claiborne Group, or Suwannee Formation chert beds along the river. What you find is brown mottled agate and a range of pastel colors from green to yellow to violet, plus chalcedony, quartz, and microminerals like jarosite and opal lining the small vugs inside the chert. It's a real, repeatedly documented local rockhounding tradition — local clubs (the Aiken Gem, Mineral & Faceters Society) have run organized field trips here — not a one-off internet rumor.

Girard sits on the Savannah River in Burke County, Georgia, near the South Carolina line on State Highway 23. The material is worked from river gravel bars and sandbars along this stretch of the Savannah.

Surface collecting on river sandbars and gravel bars — no digging required, just working exposed gravel after water levels drop. Spring through fall is the recommended season per regional sourcing; water levels and sandbar exposure vary with river flow, so check conditions before a trip.

Not applicable — this is free, informal river-corridor collecting, not a fee site.

Land status directly along this stretch of the Savannah River is unverified for this specific dossier — the river itself is a navigable public waterway, but bank ownership above the high-water line varies between private land and the Georgia DNR's Yuchi Wildlife Management Area (7,800 acres, also in Burke County). Confirm access before leaving the water's edge, and see Georgia DNR's WMA info for the surrounding public land: https://georgiawildlife.com/yuchi-wma.
