2023 Map of Peterson Ridge

USGS Topo · Published 2023

About this map

Peterson Ridge and Blalock Mtn anchor this high-elevation landscape in Umatilla County, where the headwaters of several major drainages begin their descent. The area is defined by the complex branching of Cottonwood Creek, including its North Fork, Middle Fork, and South Fork tributaries. These deep canyons are separated by high points such as Saddle Mtn and Pikes Peak, which provide significant topographic relief.
