1952 Map of Post Office Flat

About this map

Cibola National Forest encompasses the majority of this high-altitude landscape, where the Continental Divide traverses the rugged peaks of the Zuni Mountains. The terrain is defined by dramatic elevation changes, from the crest of Oso Ridge down into deep incisions like Ojo Redondo Canyon and Diener Canyon. Human presence is marked by isolated homesteads and industrial sites, including the Serna Homestead and the Sawmill (Aband) near the northern boundary. Resource extraction is evident through the Mirabal Mine and several other unnamed mine workings. The map documents a network of primitive roads connecting scattered settlements such as Copperton and Sawyer, providing a record of mid-century ranching and timber activity before more modern developments altered these remote uplands.
