The Grand Ronde Agency and the community of Grand Ronde anchor this late-1970s landscape where the timber and agricultural lands of Polk and Yamhill counties meet. The South Yamhill River cuts through the center of the quadrangle, joined by numerous tributaries such as Agency Creek and Cosper Creek. The transportation and industrial backbone of the era is evident through the path of the Longview Portland and Northern railroad, which parallels the river and connects points like Valley Junc.
