Elizabeth and William Orr finished their revision of the book OREGON GEOLOGY in 2012 and this reference/text is now available. In this 6th edition they have replaced much of the data and history of mining with sections on geologic hazards (quakes, tsunamis,landslides, floods, and volcanoes).  Organization is still by geologic province, and the Owyhee gets its own chapter now. Some of the major innovations/discoveries they record include lidar, to see through thick vegetation; and a monster new volcanic edifice, the Crooked River Caldera (35 mi. dia.!!!) centered on Prineville. Bill will present a power point show on these and other features in the book, and copies of the tome as well as OREGON FOSSILS will be available for sale.

Dr. Orr completed his baccalaureate in geology at the Univ. of Oklahoma in 1961 and his masters and PhD at the Univ. of Calif. and Michigan state respectively in 1963 and 1966. In 1997 he retired as emeritus professor from the Univ. of Oregon after 30 years service, and he still volunteers there as museum director. As a registered professional geologist he runs a consulting firm, and with Elizabeth he has written a score of books on geology, paleontology and water issues of the Pacific Northwest.
