2018 Map of Tom Thumb

About this map

Chiulikam serves as a primary point of reference in this arid expanse along the border of Maricopa and Pima counties. The terrain is defined by the Sauceda Mountains in the northwest, which transition into the broad Hickiwan Valley. The landscape is etched by drainage networks including Sauceda Wash and Hickiwan Wash, which illustrate the natural hydrology of this high desert region. Prominent landmarks such as Tom Thumb and Stinson Peak rise above the valley floor, providing essential orientation points for those navigating this remote southwestern corridor. The map effectively documents the intersection of significant topography and local watercourses in the decade following the turn of the century.
