2020 Map of Union
USGS Topo · Published 2020About this map
The Union townsite occupies the western edge of this 2020 survey, where the residential grid meets the expansive Grande Ronde Valley. This area is defined by a sophisticated network of water management, including the Catherine Cr Highline Canal and Prescott Ditch, which redirect flow from Catherine Cr to support the local agriculture. The topography rises sharply east of town into the foothills of the Wallowa Mountains, revealing a landscape of steep drainages like Pyles Canyon and high points such as Clark Mtn.
