Chroma and value may change from 0.5 to 2 units from broken face to rubbed colors. The surface tier has structure ranging from thin to thick, platy to weak, fine to coarse, granular or subangular blocky. Reaction in the middle part ranges from slightly alkaline to moderately alkaline. The subsurface and bottom tiers have weak, thin to thick, platy or weak to moderate, fine to coarse, granular to subangular blocky structure, or are massive. Some pedons have layers of fibric material ranging to as much as 5 inches in thickness.
Reaction ranges from slightly alkaline to moderately alkaline.
These are the Carlisle , Houghton , Peteetneet , Saltese , and Semiahmoo series in the same family and the Adrian , Carbondale , Edwards , Greenwood , Linwood , Lupton , Palms , Rifle , and Willette series. Adrain, Linwood, Palms, and Willette soils have less than 51 inches of organic deposits. Carlisle, Houghton, Peteetneet, Saltese, and Semiahmoo soils do not have carbonates in the control section. Edwards soils have marl within the control section. Lena soils are in bogs within lake plains, till plains and flood plains.
