The Samish series consists of somewhat poorly drained soils formed in alluvium high in talc over older alluvium. These soils are on stream terraces. Slopes are 0 to 3 percent. Samish silt loam-pasture. The series control section averages less than 15 percent fine sand or coarser and between 5 and 18 percent clay.
Reaction is medium acid or slightly acid throughout.
The A horizon has hue of 10YR, 2.5Y or neutral, value of 4 or 5 moist and dry, and chroma of 0 or 1 moist and dry. Most pedons have yellowish brown mottles. The 2Cg horizon has colors like the Cg horizon and is stratified very fine sandy loam and silt loam with some pedons having very thin strata of loamy fine sand and silty clay loam. These are the Limerick and Newalbin series. These soils lack the talc layer in the upper part of the control section.
