1894 Map of Bisuka

About this map

Initial Point, the primary survey reference for the public land system in Idaho, stands as a central landmark in this late 19th-century reconnaissance. North of this geographic anchor, the Oregon Short Line Railroad cuts across the sagebrush plains, connecting the small siding of Kuna to Bisuka and Blacks. The rail line parallels Indian Creek, tracing a path of infrastructure that facilitated early settlement in Ada County. To the south, the landscape drops sharply into the canyon of the Snake River, which serves as the boundary with Owyhee County. This riparian corridor is marked by the volcanic geology of Basalt Butte and Castle Buttes, providing a stark contrast to the high desert above. For those researching the early cattle ranching era, the map identifies isolated outposts such as Oreana and water sources like Sinker Creek and Castle Creek that were vital to the high-desert economy of the 1890s.
