Andrea Corskrey (cq), front, and Drew Bewley (cq), back, students from Western Kentucky University in Bowling Green, Ky., work on mapping a room inside of Crump’s Cave, near Smiths Grove, Ky., which is which contains a crystal blue, underground lagoon. The cave contains glyphs on the clay banks of a passage 1000 m from the entrance that is off limits to the general public. Bark from a deep incision in one of these figures produced a radiocarbon date of 30 B.C. ± 60 years (Haskins, 1994 personal communication). This date is especially significant because it is the only charcoal actually retrieved from within a glyph.
