Some pedons have stones on the surface. It is clay or silty clay. It has weak fine or medium subangular blocky structure. These are the Astoria , Blachly , Ead , Fendall , and Gleneden series. Astoria soils have amorphous materials in the exchange complex and have hue yellower than 5YR throughout.
Blachly soils have an ochric epipedon.
Ead soils also have an epipedon thicker than 20 inches. Gleneden soils are somewhat poorly drained and have matrix colors of 10YR or yellower. McCully soils are on uplands at elevations between 800 to 3,000 feet. Slopes are dominantly 4 to 30 percent but range from 2 to 70 percent. The soils formed in fine textured colluvium over fine and coarse grained, basic igneous, tuffaceous agglomerate.
