About the Author

Edward T. Luther is a native Tennessean whose professional career as a geologist and personal interest in writing have pointed him toward the preparation of this book. Since receiving his advanced degree in geology from Vanderbilt University in 1951, he has come to know that state intimately - first as a team member of the Tennessee Geological Survey and more recently as supervisor of the Survey's research program. He is also an avid reader of fiction and has long been interested in applying writing skills to his technical knowledge in order to make the fascinating science of the earth available to a wider audience.
