Geology of the County

In Meade County, water is obtained from consolidated sedimentary rocks of Mississippian age and from unconsolidated sediments of Quaternary age. Geologists call the oldest rocks found at the surface in Meade County the Salem Limestone. The most common rocks in Meade County are Mississippian limestones, deposited 350 million years ago in the bottom of a warm, shallow sea. Over the last million years, unconsolidated Quaternary sediments have been deposited along the larger streams and rivers.
