Standout geode spots in Missouri

Hand-picked from the full list below, with the reason each one earns a trip.

Alexandria & Wayland
Clark County County
Clark County is the most productive geode-collecting county in Missouri, sitting at the southwestern edge of the famous Keokuk geode district along the Des Moines and Mississippi drainages. Geodes weather out of the lower Warsaw Formation, a soft shaley limestone, and concentrate in creek and river gravels with quartz, calcite, and sulfide linings. The Alexandria and Wayland area near the Des Moines River mouth has long been a classic source.
Fabius River
Lewis County County
The Fabius River drainage in Lewis County cuts through the Warsaw Formation on the southern margin of the Keokuk geode belt, releasing geodes lined with quartz, calcite, aragonite, and trace sulfides into the river gravels. It extends the famous Clark County geode beds a county south and gives collectors a second, less-crowded drainage to work. Geodes here range from golf-ball size to grapefruit size.
