La Grande serves as the focal point of this Eastern Oregon valley, situated at the base of the Blue Mountains where the Grande Ronde River and numerous irrigation canals like Grande Ronde Ditch define the agricultural landscape. The map highlights the town's role as a regional center, featuring the campus of Eastern Oregon University and the La Grande Post Office. The surrounding terrain transitions sharply from the flat valley floor to the prominent heights of Table Mountain and Rooster Peak to the west. Irrigation is a dominant theme of the local geography, evidenced by an intricate network of waterways including Pierce Slough, Mulholland Slough, and Gekeler Slough. This detailed survey also documents several historic burial grounds, including Hillcrest Cemetery, Grandview Cemetery, and the Island City Cemetery, which provide significant value for genealogical research in Union County.
