1996 Map of Empire Ranch

About this map

Empire Ranch serves as a focal point in this high-desert landscape of Pima County, positioned at the edge of the Las Cienegas National Conservation Area. The map reveals a transition from the drainage systems of Davidson Canyon and Empire Gulch to the rising elevations of the Santa Rita Mountains and Empire Mountains. The settlement pattern is defined by isolated outposts and livestock infrastructure, including High Haven Ranch, Hidden Valley Ranch, and the Oak Tree Windmill. Mining activity is evident through the Helena Mine and numerous drill holes scattered across the terrain. Historical local activity is further marked by the presence of Greaterville in the southwest and the Rosemont Camp area, connected by a network of 4WD trails and primitive roads that navigate the complex system of gulches like Los Posos Gulch and Ophir Gulch.
