The agricultural valleys of Union County are anchored by the Grande Ronde River, which carves a winding path past the foothills of Mount Harris. This 1994 edition reveals a landscape defined by an intricate network of rural roads such as Sandridge Road and Imbler Road, serving the small farming communities of Imbler, Summerville, and Alicel. The river's original oxbows are visible alongside the engineered State Ditch, a testament to local efforts to manage the floodplain for cultivation. Family-named landmarks and infrastructure like Speckhart Lane and various Storage Bins underscore the area's deep-rooted agrarian economy. To the northwest, the settlement of Summerville is located near its namesake Summerville Cem and a historic Mill site on Willow Creek. The steep eastern ascent toward the Lookout Radio Tower provides a sharp contrast to the flat, irrigated valley floor where the Grande Ronde meanders.
