Abstract

The bedrock aquifer of the Driftless Area of northwest-ern Illinois is Ordovician Galena Dolomite. Previous work by the authors and others showed that the geology and hydrogeology of this area fall well within the defini-tion of karst. Bedrock in the study area has been shown to be extensively fractured and creviced; karst features in the county are dominated by solution-enlarged crevices from 0.4 inches to 3 feet (1.0 cm to 0.9 m) wide within most road cuts and quarries examined. Other karst fea-tures include cover-collapse sinkholes ranging from 3 to 25 feet (0.9 to 7.6 m) in diameter overlying Galena Do-lomite, karst springs and crevice caves.
