In "Cave Explorations in Missouri, Indiana, Illinois, Kentucky, Tennessee, and Alabama," Gerard Fowke, the famed American archaeologist and geologist, gives detailed accounts of the archaeological and geological histories of more than 180 caves throughout the American Midwest and South. Through in-depth descriptions and over 90 illustrations, Fowke provides readers with a look into the formation of these caves and the early people who inhabited them. This book is an excellent companion to "Caves of Missouri" by J. Harlen Bretz.
