2011 Map of Arco North

About this map

Arco and the Big Lost River Valley define the landscape of this Idaho interior, where irrigation infrastructure is as prominent as the natural waterways. The movement of water across this arid basin is meticulously documented through a network of man-made features like the Arco Canal, Island Ditch, and East Side Ditch. These systems parallel the Big Lost River as it flows past the small settlements of Moore and Lost River, illustrating the intensive management of resources required for agriculture in the high desert. To the east, the terrain rises sharply toward Arco Peak and the passage at Beaverland Pass, marking the transition from the flat valley floor to the foothills of the surrounding mountains. The presence of Hillcrest Cemetery southeast of the main settlement provides a specific point of interest for those researching local family histories in this part of Butte County.
