On August 22, Dr.  Nicholas Crawford, retired hydrologist from Western Kentucky University, will visit the Head of Sequatchie to deliver a presentation on the distinctive geological and hydrological features found in the Grassy Cove and Head of Sequatchie areas.  A leading authority on the topic, Crawford prepared an influential Ph. D. dissertation on the hydrogeology of this region.  Starting his research in 1972, his dissertation was later published in four parts by the Tennessee Division of Geology.  Crawford’s talk will explore the subterranean drainage and Karst topography of Grassy Cove and Head of Sequatchie.  He will describe his pioneering experiments using dye traces to understand how water passed under the surrounding mountains to form the magnificent Sequatchie Valley and Grassy Cove topography.
