1966 Map of Flagstaff Peak

About this map

Flagstaff Peak stands as the central landmark of this mid-1960s survey, where the borders of Sanpete, Emery, and Sevier counties converge in the Manti-La Sal National Forest. The landscape is defined by high-elevation drainage systems, including Muddy Creek and the headwaters of the East Fork Box Canyon. Evidence of early infrastructure and resource use is present at the Mine Tramway and the remote Jason Cabin, which sits near Jason Gulch. Water management for the surrounding basins is reflected in the Wrigley Springs Reservoir and smaller features like Blue Lake. The map details a complex system of canyon topography, such as The Box and The Troughs, alongside localized grazing or transit areas like The Pines and South Sage Flat, providing a clear view of the high-country activity before modern expansion.
