The rocks and landforms have not changed much since the publication of the first edition of the Roadside Geology of Colorado in 1980, but our understanding of them has. With expanded coverage, updated maps, new photographs, and the latest geologic interpretations, this nontechnical guide introduces you to the tumultuous geological history of Colorado s mountains, plateaus, and plains. The second edition includes tours of Black Canyon in Gunnison National Park, Rocky Mountain National Park, Dinosaur National Monument, Great Sand Dunes National Monument and Preserve, Mesa Verde National Park, and Florissant Fossil Beds National Monument.
