Wyoming sagebrush (Artemisia tridentata wyomingensis) and bluebunch wheatgrass (Pseudoroegeneria spicata) are the common components to shrub steppe in the central portion of the Columbia Basin. This site is in the Beezley Hills near Ephrata, Washington. The 'red' colored hillside to the right is a south-facing slope. The extra sunlight (which means warmer and drier environment) results in a different plant community, thus the color change.
