One of the broadest and most far-reaching popular geology texts, ¿Highlights of Northern Arizona Geology¿, examines prominent geologic features, explores side canyons of the Colorado River, exposes petrified wood of the Late Triassic, and culminates in an aerial tour of northern Arizona¿s volcanic fields, canyonlands, and high plateaus. Beautifully illustrated with a compact, well-written text tailored to the non-geologist interested in the origin and evolution of the Colorado Plateau of northern Arizona. Simplified geologic maps and a stratigraphic column of Grand Canyon and younger Mesozoic rock units are sure to enrich any visit to northern Arizona.
