Warsaw — Rockhounding in Benton County, Missouri

Warsaw anchors the southern end of the Benton County mozarkite belt and sits on the Harry S. Truman Reservoir, where falling lake levels expose chert and mozarkite cobbles along the shoreline. The same Burlington and Warsaw limestone weathering that supplies Lincoln also feeds gravels and lakeshores around Warsaw, yielding banded gem chert plus agate and ordinary chert. It is a second strong access point for the state rock, with miles of public shoreline to walk. Reported finds include agate, chert, mozarkite.
