1942 Map of Sierra Bonita Ranch

About this map

Sierra Bonita Ranch anchors the southeastern corner of this Graham County landscape as it appeared in the early 1940s, situated between the Galiuro Mountains and the Pinaleno Mountains. The map reveals an arid terrain deeply reliant on scattered water sources, including the marshy Hooker Cienega and numerous family-named windmills like Paddy Lynch Windmill and Wilson Windmill. This cattle-ranching territory is dotted with evidence of earlier homesteading efforts, including the Shotgun Smith Ranch and K H Ranch, both of which were already marked abandoned at the time of the 1940 survey.
