As a geologist, I have long been interested in fraud and deceit in the mining industry. Although mining fraud is rare today (unfortunately, it is not entirely gone), 100 years ago it was much more common. Until about World War I, fraud played a significant role in American mining history. But when I wanted to read more on the subject, there was no book on the history of mining swindles, so I had to write it myself. The result is A Hole in the Ground with a Liar at the Top, published in 2006 by the University of Utah Press.
