Grande Ronde River winding through the eastern slopes of the Blue Mountains defines the character of this Union County landscape. The settlements of Hilgard and Perry are established along the river corridor, where the historic route of the Oregon Trail Natl Historic Trl and modern transportation arteries navigate the narrow valley floor. To the north and south, the terrain rises into the Whitman National Forest, dissected by a complex network of drainages including Fivepoints Creek and Whiskey Creek. Higher elevations are marked by landmarks like Mahogany Mtn and the waters of Morgan Lake and Hunter Lake. The map details a transition from river-bottom ranching and transit to the timbered reaches of the national forest, with local history preserved at the Hilgard Cem.
