About this map

Hammett sits at a critical bend where the landscape transitions from high desert plateau to the fertile river bottom of the Snake River. This 2017 study illustrates a complex irrigation and transport network defined by the King Hill Main Canal and the historic path of the Old Oregon Trail Hwy. The terrain is marked by significant elevation changes, most notably at Wilson Grade and the restrictive passage known as the Narrows.

Hydrological features dominate the local geography, from the constant flow of Simpkins Spring to the braided channels surrounding Schoffs Island and Spartin Island. The map records several named drainages including Bennett Cr and Cold Springs Cr, which cut through the high ground. Local family and place names are preserved throughout the road network, including W Wicher Rd, Hammett Hill Rd, and S Mooney Ln, providing a detailed look at the rural land divisions in this part of Elmore and Owyhee Counties.
