This map, printed on four sheets, was issued in the quarto edition of Dutton's Atlas to Accompany the Monograph on the Tertiary History of the Grand Canon District - one of the most important works on the region ever produced. The map presents the geology of the Kaibab Plateau, part of the larger Colorado Plateau, which is situated just to the north of the Grand Canyon. Located within this plateau is the Ottoman Amphitheater, Bright Angel Amphitheater, and the Head of the Grand Canyon. Topography is well depicted and a key identifies 4 different geological types. Lithographed by Julius Bien & Company.
