Located in the Blue Mountains of southeast Washington State and northeast Oregon, lies the Umatilla National Forest, covering 1.4 million acres of diverse landscapes and plant communities. The Forest has some mountainous terrain, but most of the Forest consists of v-shaped valleys separated by narrow ridges or plateaus. The landscape also includes heavily timbered slopes, grassland ridges and benches, and bold basalt outcroppings. Elevations range from 1,600 to 8,000 feet above sea level.
