Base saturation is 20 to 35 percent in the lower part and ranges to 45 percent in the upper part. It is clay or silty clay. It has 0.7 to 2 percent organic matter. These are the Hazeldell , Olympic , and Seaquest series. Hazeldell soils have 15 to 35 percent rock fragments in the particle-size control section and have hue of 10YR to 5YR throughout the solum.
Olympic soils have an umbric epipedon.
Seaquest soils have a calcium to magnesium ratio of 0.3 to 1.0 in the particle-size control section. The Jory soils are on low rolling foothills. Slopes are 2 to 90 percent but are typically less than 60 percent. The soils occur at elevations of 250 to 2,500 feet. The soils formed in fine textured colluvium mainly from basic igneous materials and secondarily from tuffaceous and sedimentary materials.
