1966 Map of Chrome Butte

About this map

The rugged mining and ranching legacy of Gila County is etched into this 1966 topographic survey. Central to the map is the former silver camp of McMillanville (Site), once a bustling center for the Old Owen McMillan Mine. The terrain is defined by dramatic relief, stretching from the Apache Peaks and Richmond Mtn toward the southern edge of the Tonto National Forest. Sparse human activity is recorded through isolated outposts such as Winters Ranch and Griffin Ranch, alongside scattered corrals and water tanks essential for livestock in this arid environment.
