Book excerpt: Since the first edition of Roadside Geology of Washington appeared on the book shelves in 1984, several generations of geologists have studied the wild assortment of rocks in the Evergreen State, from 45-million-year-old sandstone exposed in sea cliffs at Cape Flattery to 1.4-billion-year-old sandstone near Spokane. In between are the rugged granitic and metamorphic peaks of the North Cascades, the volcanic flows of Mt. Rainier and the other active volcanoes of the Cascade magmatic arc, and the 2-mile-thick flood basalts of the Columbia Basin.
