About this map

Arco sits at the southern edge of this Idaho landscape, where the Big Lost River Valley meets the rising slopes of the Challis National Forest. The geography is defined by a sophisticated network of irrigation systems necessary for high-desert agriculture, including the Island Ditch, Lower Blaine Canal, and Arco Canal. These man-made features diverted water from the Big Lost River to support small agricultural settlements like Moore and Lost River.

Elevations rise sharply to the east, marked by landmarks such as Arco Peak and a Natural Arch. The intersection of wilderness and infrastructure is clear at Beaverland Pass, while the local heritage of the area is anchored by the Hillcrest Cem near the town center. This map captures the intricate water-management patterns and the grit of these mountain-shadowed communities as they appeared in 2017.
