Union serves as a central hub in the eastern Oregon landscape of 1906, situated where the foothills meet the Grande Ronde Valley. The geography is defined by a sophisticated water management and transport network, including the State Ditch and the Oregon Railroad and Navigation Co, which connects settlements like Alicel and Telocaset. In the east, the Wallowa Forest Reserve covers the high timberlands, while the Grande Ronde River winds through the valley floor near the curative waters of Hot Lake. This era shows a transition from rugged pioneer outposts to established agricultural and railroad towns, evidenced by the numerous named irrigation projects like the Coughanour Ditch and local landmarks such as Medical Springs and Horse Ranch.
