The Acoma-Zuni Section is a physiographic section of the larger Colorado Plateaus province, which in turn is part of the larger Intermontane Plateaus physiographic division. It isbounded on the east by the Albuquerque Basin, a Rio Grande Rift basin in the northern part of the Basin and Range Province. The Datil-Mogollon Section lies to the south. It is also a newly defined physiographic unit that includes the northern part of the area previously designated the Datil Section. The southeastern edge of the Colorado Plateau from Springerville, Arizona, northeastward to the tip of the Sierra Nacimiento comprises this area.
