Redoximorphic features are typically present in the C horizon and can occur in any part of the profile beneath the A horizon. This horizon typically is fine sandy loam, loam, or sandy loam, but the upper l0 inches ranges from silt loam to loamy sand. Reaction ranges from neutral to strongly alkaline. Some pedons have an AC horizon l to l0 inches thick that is intermediate in color and texture between the A and the C horizon. Thin strata of loam or loamy sand l to 3 inches thick are common in the control section.
Reaction is slightly to strongly alkaline.
In places, sand, gravelly sand or loam is below a depth of 40 inches. These are the Alda , Marksbutte Novina , Ovina , and Sunset series in the same family and the Boel , Caruso , Gibbon , and Janude soils. Alda soils have coarse sand or gravelly sand between depths of 20 and 40 inches. Marksbutte soils have gravelly sand or coarse sand at depths less than 40 inches and have salinity greater than 4 mmohs. Novina soils are moderately well drained and are not calcareous near their surface.
