These are the Bohannon , Kinney , and Preacher soils. Bohannon soils are 20 to 30 inches deep to sandstone. Kinney and Preacher soils have hue of 10YR or 7.5YR in the control section. The Hembre soils are on smooth convex ridgetops and strongly sloping to very steep side slopes of mountains at elevations of 200 to 2,800 feet in the Coast Range. The soils formed in residuum weathered from basalt and breccia.
Winter is cool and moist, and summer is warm and dry.
Mean annual precipitation ranges from 60 to 120 inches. The frost-free period is about 100 to 210 days. These are the Kilchis , Klickitat and Neskowin soils where the soil is formed in residuum from basalt. Neskowin soils have thick black A horizons. Astoria , Blachly , and Winema soils are associated where underlying rocks are sedimentary.
