These soils are usually moist, but are dry for 45 to 60 consecutive days following summer solstice. The upper part of the particle-size control section has from 8 to 16 percent clay and less than 15 percent fine sand and coarser material. The lower part of the particle-size control section is sand or loamy sand and has 0 to 35 percent channers. Depth to coarse-textured material ranges from 16 to 35 inches. Texture is loamy sand or sand.
Soil reaction is strongly acid or medium acid.
Channer size rock fragments average from 0 to 35 percent above 40 inches. Below 40 inches the substratum is stratified loamy sand to very channery sand. These are the Larush , Samish and Wickersham soils in other families. Larush soils have a cambric horizon and an umbric epipedon. Samish soils are in a fine-silty family.
