2023 Map of Jacobs Monument

About this map

Hoskinnini Mesa and Pickrell Mesa dominate this high-altitude landscape along the border of Utah and Arizona. This modern survey illustrates the complex drainage system of Copper Canyon, where the West Fork Copper Canyon and East Fork Copper Canyon converge to feed into the main channel of Copper Creek. The terrain is characterized by massive elevated formations, including the sprawling Nokai Mesa and the distinctively named Tse-dahasqani. Infrastructure in this part of San Juan County is limited to gravel routes such as SJC RD 423 and SJC RD 485, which provide access through the deep canyons and across the windswept mesa tops. This map serves as a vital record for understanding the hydrological patterns of East Copper Creek and the surrounding geological features that define the Utah-Arizona state line.
