1983 Map of Tecopa Pass

About this map

Mining operations and rugged desert camps define this 1983 study of the border region between Inyo and San Bernardino counties. The landscape is dominated by the Nopah Range, where a network of trails and the Smith Talc Road connect several notable industrial sites. The economy of the era is visible through the concentration of claims including the War Eagle Mine, Columbia Mine, and Gunsite Mine, alongside the Western Talc Mines (Abandoned). Life in this arid environment was centered around small outposts like Upper Noonday Camp and Lower Noonday Camp, positioned near topographic breaks like Tecopa Pass. Rare water sources such as Tule Spring and the drainage of China Ranch Wash provide essential landmarks in the vast basins of the Mesquite Valley and California Valley.
