About this map

The San Carlos Indian Reservation occupies the heart of this landscape, where the Gila River winds through the Gila Valley in southeastern Arizona. The settlement of Bylas stands as the primary community hub on the eastern edge of the quadrangle, featuring multiple local cemeteries and proximity to Navajo Point. Moving northwest along the Coolidge Dam Road, the smaller settlement of Calva appears near the riverbanks, marking a point of intersection between the valley floor and the surrounding high desert drainages.
