2014 Map of Porter Canyon

About this map

Porter Canyon defines the upper elevations of this Navajo County landscape, located just south of the town of Holbrook. The 2014 survey documents a transition from the structured township grid into the open drainage basins of the high desert. Modern infrastructure like Code Talkers Dr and Az-377 intersects with older routes such as Old Holbrook Rd, showing the evolution of regional transit. Water management is a primary feature of this arid terrain, with the Five Mile Reservoir and Heber Road Tank positioned to capture seasonal runoff. These features, along with Fivemile Wash and Washboard Wash, illustrate the hydrological patterns that have historically dictated land use and ranching boundaries in this part of Arizona.
