Smith Ferry and the isolated settlement of Ola serve as primary anchors in this early survey of the rugged interior between the Washington and Boise county lines. The landscape is defined by a series of high-altitude basins and distinct topographic corridors, including Upper Squaw Creek Valley, High Valley, and Sage Hen Valley. Industry and early pioneer infrastructure are represented by Walker Mill, while local landmarks like Hot Springs and Collyer Peak suggest the varied character of the terrain. The eastern edge is dominated by the North Fork Range, shielding Long Valley and Round Valley. This reconnaissance mapping, based on 1891 field work by A.H. Thompson, documents a time before significant infrastructure development, when the North Fork Payette River and small settlements like Alpha were the primary waypoints for travelers in these interior Idaho mountains.
