In the Umatilla Dissected Uplands, the dry grasslands of the Columbia Plateau (10) meet the forested Blue Mountains (11). The steep, dissected hills and terraced uplands are covered with Idaho fescue, bluebunch wheatgrass, and Sandberg bluegrass. Near the Blue Mountains, some north-facing slopes have Douglas-fir and ponderosa pine. Ecoregion 10n is mostly used as rangeland because it lacks the thick, arable loess deposits that cover the agricultural Umatilla Plateau (10c). Scablands, composed of arrays of earth mounds surrounded by rock polygons, are relics of Pleistocene glacial periods.
