Kentucky Geodes... Kentuckians like my brother Mike, his wife Bonnie and their family, have grown up around geodes their whole lives where they are used as door stops and yard decorations. Because of this, most Kentuckians probably don’t realize that people in many areas have never heard of them. That's because geodes, though distributed widely, are very concentrated in Kentucky, Indiana, Iowa and Missouri; probably for some of the same reasons that caves are so plentiful here.
Lake Cumberland was created with the completion of Wolf Creek Dam in 1951. My grandparents were farmers in Russell Springs and my grandmother always had a large rock on her front porch. When we got older and were becoming rockhounds my grandmother gave this rock to Chris and told us that it came from a section of their old farmland in Jabez that is now at the bottom of Lake Cumberland. My grandmother had brought that one rock as her keepsake of their old farm.
She decorated around her shrubs with what she called “Puddin Stones” (we got a few) which are Kentucky Geode/Nodules made of quartz and galena. Grandma Thomas did not use her rocks as her doorstop…...she had a plaster Indian there.

Quartz and Galena
Geodes are spherical or oblong rocks filled or partially filled with minerals. When a geode is broken the minerals inside are revealed. Most geodes are completely filled with minerals, most often quartz. The quartz can be massive, crystalline, or layered, which is a variety called agate. But when most people think of geodes they think of spherical rocks that are hollow. Hollow geodes have an outer shell or rind of quartz, most often the variety chalcedony. The chalcedony often has a bumpy or lumpy appearance from the outside. But the bumpy appearance is no assurance that the inside of the spherical rock will be hollow. Solid Geodes are referred to as Nodules.
The interior of hollow geodes are filled with mineral crystals, which grow inward from the rind into the hollow space inside the geode. Most often, geodes found in Kentucky are lined with quartz crystals. Less commonly, the calcite or dolomite crystals are found on the inside, either alone or associated with bitumen, barite, galena, fluorite, quartz, limonite, sphalerite, pyrite, selenite, or celestite.
Geodes differ from concretions in that they are hollow and the crystals grow inward from an outer shell. Concretions are solid and grow outward from a central core. Concretions are generally noncrystalline.
The Fort Payne and Warsaw-Salem Formations, rock units of Mississippian age, contain numerous geodes in Kentucky. In many places, creeks that drain these formations are filled with geodes. Other geode-collecting locations include the Green River in south-central Kentucky and along ancient terraces of the Kentucky River. The Green River has produced some very large geodes up to 2 feet in diameter.
