1956 Map of San Lorenzo

About this map

San Lorenzo and San Juan anchor the lower Mimbres Valley in this mid-century survey, a landscape defined by the drainage network of the Mimbres River and East Fork Mimbres River. The terrain transitions from the valley floor into the steep reaches of the Gila National Forest, where the Black Range forms a high eastern barrier. This area was a hub of resource extraction, evidenced by the concentration of high-altitude mining operations such as the Rose Mine, Columbia Mine, and the Grandview Mines near Sawyers Peak.
