1963 Map of O Block Canyon

About this map

The San Francisco River cuts a deep, winding path through the high country of the Gila National Forest in this 1963 survey. The landscape is defined by the elevation gains of the Saliz Mountains and the Kelly Mountains, where remote infrastructure like the K Kelly Ranch represents the rare human footprint in this interior wilderness. Historical movement through the area is traced via established routes such as the Frying Pan Trail, a Pack Trail, and the Beaverhead Road. The map documents a network of water management features essential for ranching and forest maintenance, including Frisco Plaza Tank No 2, Trail Tank, and Devils Park Tank. Topographical landmarks like Apache Peak and the curiously named Hells Hole Canyon highlight the geographic complexity of the O Block region before modern developments reached this part of New Mexico.
