Burlington (geodes) — Rockhounding in Des Moines County, Iowa

Updated July 2026

Burlington marks the transition between Iowa's two great rockhounding stories: the Keokuk geode belt to the south and the Lake Superior agate fields carried in by glaciers. Mississippi River gravel bars here concentrate banded Lake Superior agates and quartz alongside the occasional geode weathered from nearby Mississippian limestone. The mix of glacial and bedrock material makes a single gravel bar unusually varied. Reported finds include lake superior agate, quartz, geode.
