FOREWORD The West Texas State University Geological Society was organized in 1958 by students of the Department of Geology. The objective of the Society is to promote interest in geology as an academic subject and as a professional career. In order to present the concepts of geology to interested groups, the Palo Duro Canyon Guidebook is sponsored by the WTSU Geological Society. The Geological Society is indebted to Professor Jack T. Hughes and to Mr. Jerry Harbour for their work in the first edition of this guidebook. DO YOU HAVE A GROUP OR KNOW OF A GROUP WHO WOULD LIKE A GUIDED FIELD TRIP OF PALO DURO CANYON?
