About this map

The Snake River carves a deep valley through this desert landscape, defining the border between Elmore and Owyhee counties. The small settlement of Hammett serves as the focal point for local infrastructure, where the King Hill Main Canal and the historic Old Oregon Trail Hwy parallel the river's northern bank. This corridor is rich with named landmarks like Schoffs Island and Sparlin Island, as well as the distinctive passage known as The Narrows.

Surface water management is evident throughout the southern desert plateau, with Sailor Creek and Cold Springs Creek draining toward the river. Transportation history is layered here, with contemporary routes intermingling with Old Hwy 30. The map also details the rugged ascent of the Wilson Grade and local family-named roads such as W Bernt Rd and S Mooney Ln, reflecting the enduring agricultural and ranching footprint of the region.
