1990 Map of Black Peak

About this map

Black Peak rises as the dominant landmark in this arid landscape, a prominent summit anchoring the northern edge of the terrain. The eastern reaches of the Colorado River Indian Reservation dominate the western half of the map, illustrating the intersection of tribal lands with the open desert of Arizona’s La Paz County. Two significant drainage systems, Osborne Wash to the north and Bouse Wash to the south, define the hydrological patterns of the area, though they remain seasonally dry. Modern infrastructure is evident through the presence of a large-scale transmission line and an aboveground pipeline that traverse the desert floor, alongside Radio Facilities situated near the peak. The inclusion of a lone Well suggests the critical importance of water access for ranching or surveying in this isolated desert environment during the late twentieth century.
