2023 Map of Threemile Hill

About this map

Jordan Creek meanders across this corner of Malheur County, carving a path through an arid landscape defined by managed water and volcanic terrain. The intricate network of the North Side Canal and South Side Canal illustrates the intensive water management required in this region, feeding into various catchments like Saddle Butte Reservoir and the Hidden Reservoir. Elevation is marked by the prominent Threemile Hill and the escarpment of Merrill Springs Rim, while the presence of the Lequerica Trap suggests historical livestock management in the high desert. Historically significant routes such as the Old Ion Hwy and Lava Beds Rd provide the primary access through this sparsely populated territory, linking the remote cattle country and canyonlands of eastern Oregon.
