1996 Map of Tillotson Peak

USGS Topo · Published 2000

About this map

The Valley of the Ajo dominates this high-desert landscape as it appeared in the late 1990s, flanked by the prominent heights of Tillotson Peak and the Puerto Blanco Mountains. This survey documents a critical portion of the Organ Pipe Cactus National Monument, where the environment is defined by expansive drainage systems like Alamo Wash and Cherioni Wash. Human activity is concentrated along the Puerto Blanco Drive and Alamo Canyon Rd, while the eastern portion of the quadrangle is largely protected under the Organ Pipe Cactus Wilderness designation. Traces of early prospectors are found near Eagle Pass, where scattered sites including an Adit and various prospect pits indicate the history of mineral exploration in these arid peaks. Notable summits like Pinkley Peak provide topographic anchors for a region defined by its conservation status and rugged isolation.
