||The year 1997 marked the twenty-fifth anniversary of the Roadside Geology Series. With nearly one million Roadside Geology books sold, Mountain Press strives to preserve the original intent of the series -- to provide scientific information in an engaging and accessible way for everyone interested in how the earth works. Professional geologists write and edit the Roadside Geology books for people who are not geologists but would like to learn something about the rocks and landforms around them. Each book begins with an introductory chapter that briefly reviews the rocks and landscapes of its state. The remaining chapters provide a detailed discussion of state regions and end with a series of road guides. All Roadside Geology books are in a paperback, six-by-nine format and include maps, photographs, and illustrations.
