About this map

The Aubrey Cliffs dominate the eastern landscape of this Coconino County terrain, creating a sharp geological divide against the flat expanse of the Aubrey Valley to the west. This 1981 record captures a corner of the Arizona high country where land use is defined by water management in a semi-arid environment. The distribution of small water catchments, such as Big Chief Tank and Antelope Tank, reflects the essential infrastructure for ranching and livestock in this remote basin. Survey markers like the Pica Azimuth Mark No 2 and the South Twin Azimuth Mark are anchored to prominent high points, including South Twin, providing fixed reference points for cartographers and land surveyors. To the southeast, the topography descends into Rhodes Canyon, illustrating the drainage patterns that define the edge of the plateau.
