2018 Map of Sentinel

About this map

Sentinel sits as a lonely outpost along the southern transcontinental transportation corridor in this high-desert region of Maricopa County. The landscape is defined by its vast openness and the long, linear trajectories of infrastructure that cross it, including the modern paths that parallel the historic Southern Pacific route. S Agua Caliente Rd strikes out from the settlement, cutting diagonally across the township lines of t7s r10w, t7s r9w, and t6s r10w. The sparse arrangement of labels reflects the arid nature of the terrain, where water and transit have historically dictated the location of every permanent structure. This 2018 study captures the geometric precision of the Public Land Survey System, dividing the desert into the regular blocks of t8s r9w and surrounding ranges that characterize this remote corner of Arizona.
