These are the Klickitat and Witzel series in other familes. Klickitat soils are deeper than 40 inches to bedrock. Witzel soils are dry for more than 45 consecutive days between depths of 4 and 12 inches and have base saturation greater than 50 percent throughout the sola. The Kilchis soils are on very steep slopes of the Coast and Cascade Range at elevations of 500 to 4,000 feet. The soils formed in colluvium derived from basalt and breccia.
Winter is cool and moist and summer is warm and dry.
Mean annual precipitation is 60 to 120 inches. The frost-free period is 100 to 210 days. These are the Hembre , Trask and the competing Klickitat soils. Hembre soils contain less than 50 percent rock fragments and are more than 40 inches deep to bedrock. Trask soils have hue of 10YR or 7.5YR and they are more than 20 inches deep to bedrock.
