2020 Map of Arock

About this map

Jordan Creek meanders through this portion of Malheur County, anchoring a landscape defined by water management and remote settlement. The small community of Arock sits near the eastern edge of the quadrangle, serving as a focal point for local history alongside the nearby Arock Cem. This area of eastern Oregon is characterized by a complex network of irrigation and storage, including the N Side Canal, S Side Canal, and several named catchments like Juniper Tree Reservoir and No Catchum Reservoir. These features highlight the effort to manage scarce water resources for ranching and agriculture. The terrain rises to landmarks such as Grahams Hill and Merrill Springs Rim, while Hidden Valley lies tucked away near the creek's path. Historic transit routes like the Old Ion Hwy and Bogus Ranch Rd provide the primary infrastructure through the arid canyons and basins.
