1964 Map of South Mountain

Evidence of early livestock and land management is found at Lone Mesa Reservoir and the nearby Lone Mesa Spring No 1 atop the broad Lone Mesa plateau. For genealogists, the map preserves the location of Nash Cem near the northern boundary. The rugged character of the area is highlighted by a sparse network of roads, with a primary Jeep Trail serving as one of the few named routes through the timbered slopes and creek bottoms.
