About this map

The borderlands of Whitman National Forest and Umatilla National Forest converge in this high-elevation landscape, where the administrative boundaries of Umatilla and Union counties shift across the terrain. This is a region defined by complex drainage networks, where Meadow Creek and McCoy Creek carve through the timbered uplands. The presence of numerous named springs, such as Tamarack Spring, Jungle Spring, and McClellan Spring, indicates a geography where water sources were critical for forest management and local ecology.

Notable landmarks like McClellan Meadow and the deep incisions of South Canyon and Dark Canyon illustrate a land shaped by steep vertical relief. The map reveals how local names—Tamarack Gulch, Klondike Spring, and Pearson Creek—have become fixed points in the wilderness. For those studying the management of the Pacific Northwest's national forests, this survey documents the late twentieth-century state of these public lands before modern environmental shifts altered the forest's composition.
