1986 Map of Placer Canyon

USGS Topo · Published 1987

About this map

The Eagle Mountain Mine and its sprawling Central Deposit dominate the southern portion of this desert landscape, illustrating the intense industrial footprint of iron ore extraction in the mid-1980s. This survey captures the intersection of heavy industry and conservation, where the mining operations sit adjacent to the protected lands of Joshua Tree National Monument and the Joshua Tree Wilderness. The contrast between the excavated terrain and the undisturbed reaches of the Pinto Basin is stark, marked by several smaller historical workings like the Mystery Mine, Black Eagle Mine, and Cactus Mine. Localized water sources, critical for both mining and survival in the Eagle Mountains, are identified at Black Eagle Well and Eagle Tank. Steep drainages like Placer Canyon and the broad Pinto Wash define the natural drainage patterns of this arid interior.
