About this map

The Browns Gulch Mining District dominates the northern reaches of this map, revealing a landscape defined by intensive late-20th-century extraction efforts. Numerous workings like the Eastern Pacific Mine, Marietta Mine, and the General Shafter Mine are scattered across the high ridges, accompanied by various adits and mine shafts. This network of operations suggests a period of sustained interest in the mineral deposits of the Gravelly Range and Greenhorn Range, where industrial infrastructure is etched into the steep gulches.
