1966 Map of Chrome Butte

About this map

McMillanville (Site) serves as a focal point of historical interest in this mid-1960s survey of central Arizona. This former mining settlement, accompanied by the nearby Old Owen McMillan Mine, underscores the area's prospecting legacy. The landscape is split between the Tonto National Forest and the San Carlos Indian Reservation, with the boundary running through high-elevation terrain including Apache Peaks and Richmond Mtn. Human activity is concentrated along the drainages of Sevenmile Wash and Commerman Wash, where scattered locations like Winters Ranch, Griffin Ranch, and the Jones Water Campground provide evidence of rural habitation and land use. Numerous Jeep Trails wind through the canyons, connecting remote points such as Chrome Butte and Steer Mountain to the few established roadways.
