About this map

The Umatilla National Forest dominates the northern reaches of this landscape, where the high ridges of the Blue Mountains descend toward the fertile Grande Ronde Valley in the south. This transition from timbered heights to valley floor is marked by a complex network of drainages including Phillips Cr, Smith Cr, and Dry Cr, which carve deep canyons such as Moonshine Canyon and Jack Canyon.

A network of forest development roads and trails, including the Rocky Ridge Indian Tr, provides access to landmarks like Indian Point and Huckleberry Mtn. The southern half of the map reveals the hydrological management of the valley fringes through features like the Jarvis Ponds and Feik Reservoirs. Local family names are preserved throughout the terrain on Pfefferkorn Ridge, Smith Ridge, and at Sanderson Spring, reflecting the area's history of settlement and ranching along the Umatilla and Union county line.
