2020 Map of Malheur Butte

About this map

Malheur Butte rises as a prominent volcanic landmark overlooking a landscape defined by the sophisticated water management systems of eastern Oregon. This 2020 record of the Malheur County region illustrates how the Malheur River and the extensive Owyhee Canal network dictate the layout of local agriculture and settlement. The intricate system of waterways, including the Malheur Siphon, Brosnan Ditch, and Blanton Drain, weaves through the valley floor to support the communities of Ontario and Ontario Heights. To the south, the Ontario Municipal Airport serves as a modern transportation hub, while the northern terrain is broken by the deep incisions of North Fork Jacobsen Gulch and Coyote Gulch. The map meticulously details the intersection of high-desert geology and irrigation engineering that has shaped this border region.
