Questioning the Delphic Oracle
John R. Hale, Jelle deBoer, Jeffrey Chanton, and Henry Spiller 2003 Scientific American v. 298. no. 2, p. 66-73
A wonderful detective story that deals with locating and mapping faults in the field and migration of fluids with dissolved, intoxicating volatiles through permeable fault zone rocks. The connection to human events (the Delphi Oracle) is a lovely bonus. Because it is a Scientific American article, students find it very readable.
