This all-new second edition is updated by Halka Chronic and Felicie Williams. The rocks and landforms have not changed much since the publication of the first edition of Roadside Geology of Colorado in 1980, but our understanding of them has. With expanded coverage, updated maps, new photos, and the latest geologic interpretations, this nontechnical guide introduces you to the tumultuous geological history of Colorado's mountains, plateaus, and plains.

This second edition includes tours of Black Canyon of the Gunnison National Monument, Rocky Mountain National Park, Dinosaur National Monument, Great Sand Dunes National Monument, Mesa Verde National Park, and Florissant Fossil Beds National Monument.

Paperback; dimensions are 5 7/8" by 9" by 1"; 334 pages.
