2020 Map of Arco North

About this map

Arco serves as a critical geographic anchor at the southern edge of this Idaho survey, where the Butte County Courthouse marks the local seat of government. The landscape is defined by the transition from the high elevations of the Challis National Forest and Arco Peak to the agricultural expanses of the Big Lost River Valley. Water management is central to the valley's development, evidenced by an intricate network of irrigation features including the Island Ditch, Arco Canal, and Lower Blaine Canal. These systems divert water from the Big Lost River to support the surrounding settlements of Moore and Lost River. In the rugged northern terrain, landmarks such as Beaverland Pass and a Natural Arch underscore the area's geological character, while the presence of Hillcrest Cem near the town center provides a point of interest for genealogical research.
