2023 Map of Kelton Pass

About this map

Kelton Pass serves as the topographic bridge between the Raft River Valley and the Curlew Valley, marking the high point of a historic travel corridor through the high desert. This 2023 survey details the transition from the Sawtooth National Forest into the basin lands of Box Elder County, Utah, and Cassia County, Idaho. The settlement of Hardup sits on the edge of the southern valley, while the higher elevations are defined by the Raft River Mountains and the Black Pine Mountains. A series of water sources including Emigrant Spring, Crystal Spring, and Duffy Spring trace the routes of early travelers and livestock through this arid environment. The map also records landmarks like Crystal Peak and the drainage of Tenmile Creek, highlighting the importance of every permanent spring in this high-altitude landscape.
