About this map

The Umatilla River valley serves as the central artery for this 1983 landscape, where the Union Pacific railroad and Interstate 84 trace a path through the transition from high plateau wheat country to the timbered slopes of the Umatilla National Forest. The regional hub of Pendleton is documented with its major civic anchors, including Blue Mtn Community College, the State Hospital, and the Pendair Heights area near the Pendleton Municipal Airport.

Beyond the city, the map details a network of smaller agricultural settlements and rail stops such as Athena, Weston, and Helix. The southern portion of the sheet reveals the complex topography of the Blue Mountains, featuring numerous ridges like Stumbough Ridge and Bobsled Ridge, alongside protected lands including Emigrant Springs State Park and the Mc Kay Creek National Wildlife Refuge. This edition captures the infrastructure of the Umatilla Reservation and the irrigation-fed agriculture supported by the McKay Reservoir.
