Lowell — Rockhounding in Henry County, Iowa

Updated July 2026

Lowell sits in the heart of the Keokuk geode district, where the Mississippian Warsaw Formation sheds hollow, quartz-lined geodes into the Skunk River and its tributary creeks. The geode is Iowa's state rock, and this corner of Henry County is its type region, producing crystal-lined cavities of quartz and calcite with occasional pyrite, marcasite, and goethite. Fresh geodes weather steadily out of the gray Warsaw shales into the creek gravels. Reported finds include keokuk geode. Below: coordinates, access notes, nearby spots, and trip-planning links.
