About this map

Union sits at the eastern edge of the Grande Ronde Valley, serving as a transition point between the flat agricultural lands and the rising slopes of High Valley and Clark Mountain. This 1994 revision traces the town's established infrastructure, including the Eastern Oregon Livestock Exhibition Grounds, the High Sch, and the local Cem. The landscape is defined by the drainage systems of Catherine Creek and Little Catherine Creek, which cut through the uplifted terrain to the southeast.

Water management and resource extraction are evident through the presence of a Gaging Sta along the creek and several Gravel Pit sites near the valley floor. High-elevation plateaus like Ramo Flat and the steep passage of Pyles Canyon illustrate the topographical constraints that shaped local transport, with numerous 4wd tracks providing access into the timbered uplands and toward various unnamed Spring sites.
