1972 Map of Arco Hills

About this map

Challis National Forest covers the northern reaches of this high-desert landscape, where the southern tip of the Lost River Range meets the volcanic terrain of the Arco Hills. This 1970s survey details a region defined by its reliance on scarce water sources, evidenced by named features like Walker Spring, King Spring, and Combe Reservoir. The map illustrates a complex network of drainage systems, including Horsethief Canyon, Sutton Canyon, and Braithwaite Canyon, which carve through the arid topography toward Deadman Flat in the southeast. While devoid of major settlements, the presence of various corrals and the Well label suggest a history of seasonal livestock grazing and resource management in this part of Butte County.
