About this map

Post Office Flat and the surrounding high country of the Zuni Mountains define this section of the Cibola National Forest. The landscape is dominated by the Continental Divide, which separates the drainage systems of the region, including Bluewater Cr and numerous rugged canyons such as Diener Canyon and Alamosa Canyon. The presence of scattered settlements like Copperton, Sawyer, and Diener reflects the remote residential and ranching history of these uplands.

Water sources are vital features in this arid environment, marked by reliable points like Post Office Flat Spring, Serna Spring, and Rock Spring. The terrain transitions from the high peaks of Oso Ridge to the broad expanses of Salitre Mesa, accessible by a network of forest roads including Forest Rd 50 and Forest Svc 480 Rd. This modern survey records the enduring layout of township boundaries and topographical landmarks within Cibola County.
