Yes, Mammoth Cave is in Hart County, an Appalachian Regional Commission county, part of a kind of western appendix to the ARC map in the hilly hinterland west of the highest elevations. The “dating” referred to in the title is figuring out how old various features of Mammoth Cave are, not romantic adventures in the Cave. “This eclectic book delighted me from the title page to the end matter. Olson’s playful voice and sense of humor lured me along, and now I’ve a good layperson’s education in Mammoth Cave lore, cave science, and cave history.” - Wes Berry. This is the fourth book on the cave by the author, Colleen O’Connor Olson, who has served as a tour guide there for more than twenty years.
