Colville National Forest
The Colville National Forest spans 1.1 million acres in the northeast corner of Washington State. The area includes three mountain ranges -- the Okanogan, Kettle River, and Selkirk -- which are considered foothills of the Rocky Mountains.

The forest was first shaped over 10,000 years ago by Ice Age glaciers that carved three major valleys of today's Columbia, San Poil-Curlew, and Pend Oreille River flowing north into Canada before entering the Columbia River.
