Rocks, Minerals, and Geology of the Pacific Northwest

This handsome addition to the publisher’s “Pacific Northwest” field guide series, which, up to now, has focused on that region’s flora and fauna, emphasizes basic geology and has a textbook feel—not surprising, given the authors’ pedagogical backgrounds. Moclock was a museum curator involved in outreach; Selander teaches college-level geology. The book begins with a discussion of “earth-size” theories (e.g., plate tectonics, geologic time scale), and the Pacific Northwest’s 13 physiographic regions are mapped and explained. Next come chapters on minerals and rocks, with 50-odd specimens presented for each. Minerals are organized by chemical composition, and lists of key features are supported with color, often full-page photographs; mineral property tables help identification. General information on the rock cycle begins the next section, followed by detailed description of specimens from igneous, sedimentary, and metamorphic groups. Here and throughout the book, hand drawings illuminate important concepts. Short chapters on meteorites and fossils round out its “rock-in-hand” quick identification component. Discussions of structural geology and geomorphology follow, explaining the area’s outcrops and surface landscape features. The book closes with a “geologic story” of the region—a fine demonstration of one of the volume’s key lessons about “how geology is expressed at different scales.”
VERDICT Geologists both amateur and expert, rock hounds, geo-travelers
