Of all the natural history disciplines, many aspiring naturalists find geology to be one of the toughest nuts – or perhaps more appropriately, rocks – to crack. Fortunately for those aspiring to learn the subject in Oregon the sixth edition of Oregon Geology by Elizabeth L. Orr and William N. Orr has recently been published by Oregon State University Press. The first update to the work since 2000, the sixth edition incorporates a wealth of recently discovered information about just how active the ground beneath the feet of those dwelling in the “Pacific Wonderland” truly is.
