1992 Map of Twin Sisters

USGS Topo · Published 1992

About this map

The Continental Divide snake-runs through this high-elevation section of the Gila National Forest, defining the watershed of the Pinos Altos Range. This landscape is marked by the remnants of 19th-century resource extraction, notably an Arrastre for ore processing near several mining Prospects in the southwest corner. The rugged peaks of the Tadpole Pinos Altos Range, including Signal Peak and Black Peak, dominate the central topography. Recreational and commemorative sites are established throughout the forest, including McMillan Campground, Pine Flats Campground, and the Ben Lilly Memorial. Water is sparse but vital, flowing through drainages like Bear Creek, Trout Creek, and the namesake Twin Sisters Creek, while old transportation routes like the Sawmill Wagon Road hint at the area's timber and freight history.
