Alexandria & Wayland: Geode Digging in Clark County, Missouri
Updated June 2026
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. Reported finds include geode. Below: coordinates, access notes, nearby spots, and trip-planning links.
