About this map

Arco and the village of Moore anchor this survey of the eastern Big Lost River Valley, where the high peaks of the Lost River Range meet the valley floor. The landscape is defined by an intricate network of irrigation engineering, including the Arco Canal, Munsey Ditch, and Island Ditch, which divert water from the Big Lost River to support agriculture in this arid high-desert environment. These watercourses trace the settlement patterns established long before modern mapping, following the natural contours of the land beneath the looming Arco Peak.

Public administration and conservation are central to the area's identity, evidenced by the Butte County Courthouse in the heart of Arco and the sprawling northern reaches of the Challis National Forest. For those tracing local history, the map identifies local landmarks such as Hillcrest Cem and the topographic bottleneck of Beaverland Pass, providing a clear view of how the early road system, like King Mountain Rd, navigated the transition between mountain and basin.
