Lowell
Public
Henry County
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.
