2014 Map of Malheur Butte

About this map

Malheur Butte rises as the dominant volcanic landmark in this high desert landscape, overlooking a complex network of irrigation that has transformed the valley floor. The map documents an intricate hydraulic system essential to local agriculture, including the Owyhee Canal, the Malheur Siphon, and specialized channels like Brosman Ditch and the Halliday Drain. These features support the expansion of Ontario and the residential area of Ontario Heights, where the transition from open range to organized settlement is visible in the grid of boulevards and avenues.
