About this map

Black Hills and the surrounding desert terrain of Pima County are defined by their isolated peaks and the sparse network of tribal routes crossing the landscape. This part of the Tohono O'odham Nation is mapped with precise contour intervals that reveal the complex geography of Proctor Hill and the northern reaches of the Vaca Hills. The area remains largely undeveloped, characterized by wide stretches of open land and the Sil Nakya Hills on the western edge.

Transportation through this arid region relies on unpaved corridors such as Indian Rte 34 and Indian Rte 35. These routes provide essential access through several townships, including t14s r7e and t15s r6e, where the topography transitions from flat valley floors to the distinctive volcanic-looking formations of the hills. The map serves as a detailed record of land management and natural elevation in a remote part of the Southwest.
