The Yakima Fold belt is a series of unforested anticlinal ridges and synclinal valleys covering the western Columbia Plateau (10). Only the far eastern end of the ecoregion enters Oregon east of Wallula Gap on the Columbia River. The ridges are composed of layer upon layer of basalt up to 12,000 feet thick. Loess blankets the south-facing slopes and supports dryland wheat farming, while grazing occurs on steep, rocky north slopes. Located in the rain shadow of the Cascade Range, The Yakima Folds ecoregion receives little precipitation. Sagebrush and bunchgrass associations dominate plant communities outside of heavily farmed or grazed areas.
