1969 Map of Big Rock Flat

About this map

Reeds Mill and Parkers Mill sit along Three Rock Creek in this late 1960s survey of the high plateau region in Morrow and Grant Counties. Much of the southern landscape is dominated by the Umatilla National Forest, where a network of family-named landmarks such as Harrington Spring, Shaner Spring, and Davidson Canyon indicates the deep history of ranching and resource use in the Oregon interior. The map illustrates a high-desert environment where water is the primary organizing force, evidenced by the high density of named seeps like Morphine Spring, Sperry Spring, and Opal Spring. The isolated Big Rock Flat Airstrip on Big Rock Flat suggests the vast distances of this terrain, while Anson Wright Memorial Park serves as a lone recreational landmark near the western boundary along Route 207.
