About this map

Empire Ranch serves as the focal point for this area of Pima County, situated at the eastern edge of the Coronado National Forest. This landscape is defined by its ranching heritage and early mining activity, with settlements like Greaterville and Rosemont Camp appearing alongside legacy sites such as the Helena Mine. The terrain is deeply incised by drainage networks including Davidson Canyon and Empire Gulch, where water sources like Rosemont Springs and Oak Tree Windmill were essential for sustaining cattle and homesteads.
