Hurlburt Flats and the deep incisions of Eightmile Canyon define this high plateau landscape in Gilliam County. The map captures a crucial corridor of western migration, clearly marking the path of the Oregon Tr as it traverses the southern sections of the quadrangle. This historic overland route is juxtaposed with the mid-century industrial presence of the Union Pacific railroad, which follows the winding course of Willow Creek through the northeastern corner.
