About this map

The San Francisco River meanders through the heart of this high-country landscape, carving through canyons and flanking the western slopes of the Saliz Mountains. This 2011 survey captures a terrain defined by stock management and ranching infrastructure, where water sources like Saliz Tank, Frying Pan Tank, and Frisco Plaza Tank Number 2 are essential landmarks. The presence of the K Kelly Ranch and names like Kelly Mountains and Kelly Brushy suggest a long-standing ranching legacy centered around the river valley and its adjacent grazing lands.

Industrial and transport corridors are represented by rugged routes like Kelly Rd and Sign Camp/Canyon Rd, which provide access to the remote peaks of Black Mountain and Apache Peak. In the southern reaches, the topography becomes increasingly complex as drainage systems like Devils Canyon and North Fork Devils Creek converge near Devils Park, creating a network of deep incisions including Hells Hole Canyon.
