2021 Map of Split Rock

About this map

The Sweetwater River winds through this high-altitude landscape where history is etched into the terrain of the Granite Mountains. This 2021 survey traces the critical corridor of the Oregon Trl and the California Emigrant Rd, pathways that fundamentally shaped the westward expansion of the United States. Distinctive landmarks such as Split Rock and Castle Rock served as vital navigation points for pioneers crossing the high plains. The map reveals the intricate drainage patterns of Lankin Cr and Cottonwood Cr, alongside modern agricultural infrastructure like the McIntosh Beaton Ditch. Remote features like Beaton Pocket and the Great Stone Face suggest a landscape named by those who lived and worked among these granite outcroppings.
