Tampico serves as the primary settlement hub in this valley landscape defined by the convergence of the North Fork and South Fork Ahtanum Creek. The area is framed by the significant topographical features of Cowiche Mountain to the north and Ahtanum Ridge to the south. A complex network of irrigation and water management is evident through features like John Cox Ditch, Shaw Knox Ditch, and Lesh Ditch, highlighting the agricultural foundation of the region. The map also identifies Stevenson Dam and several springs, including Oak Spring, which indicate the vital role of water resources in this part of Yakima County. Transportation is marked by a grid of rural roads and lanes such as Ahtanum Rd and Cottonwood Canyon Rd, connecting dispersed homesteads and farms tucked between the ridges.
