Primary structure is moderate or strong prismatic, and consistence is firm or very firm, and brittle. Reaction ranges from strongly acid to neutral. The 2C horizon has the same range in color and texture as the Bx horizon except some pedons are sandy loam below 40 inches. The horizon is massive and may have has plate-like divisions. Consistence is firm or very firm.
Reaction ranges from moderately acid to moderately alkaline.
The Amboy and Williamson series are in the same family. Amboy and Williamson soils developed in very deep silty lacustrine deposits and lack rock fragments in the Bx and C horizons. The Bath , Mardin , Lackawanna , and Wellsboro are similar soils in a related family. The Canaseraga soils formed in silt-mantled till deposits. They are mainly on lower slopes of large valleys, but locally on moraines that cover the valley floors.
