2021 Map of O'Neill Hills

USGS Topo · Published 2021

About this map

O'Neill Hills and the rugged Agua Dulce Mountains dominate this stark desert landscape along the southern edge of Arizona. This modern survey illustrates a remote borderland where the topographical contours of Davidson Canyon and the dry course of Papago Wash carve through the arid terrain. The map is defined by its position on the international boundary, clearly marking the line between the United States of America and Estados Unidos Mexicanos. Navigating these ridges requires passage through O'Neill Pass, a critical point of movement in a region otherwise characterized by isolated peaks and shifting desert drainage. The boundary between Yuma and Pima counties also traverses this area, highlighting its role as a jurisdictional crossroads in the deep Southwest.
