The Grande Ronde Valley floor serves as the central focus of this mid-1960s survey, dominated by a grid of agricultural lanes and the path of the Union Pacific railroad. The small community of Imbler sits as a primary junction, while the meandering Grande Ronde River and the engineered State Ditch highlight the ongoing management of the valley's water resources. To the east, the terrain rises sharply toward the lookout on Mount Harris, providing a stark contrast to the level fields where Summerville and Alicel are established. Genealogists and local researchers can locate the Summerville-Imbler Cem and several family-named landmarks, such as Mc Kenzie Lane and Hull Lane, which define the property lines and rural settlement patterns of Union County during this era.
