About this map

The Gila River winds through the heart of the Gila Valley, defining the geography of this Graham County landscape. Centered on the settlement of Calva, the terrain is heavily marked by seasonal drainage systems and deep cuts, including Wildhorse Canyon, Bone Spring Canyon, and the prominent Calva Draw. These features reflect a landscape shaped by water in an arid environment, where isolated water sources like Poison Spring were likely critical for early ranching and travel.

Transportation through the valley is anchored by Coolidge Dam Rd, which follows the river's southern bank, and several county routes such as Yellowjacket Rd and Co RD 213. Significant topographic markers like Navajo Point and Bates Draw rise above the basin floor, providing a detailed look at the area's relief and historical land divisions. This survey preserves the exact road network and wetland boundaries along the river corridor as they existed in the late 2010s.
