Indicator B70: Drainage patterns Category: Secondary General Description: This indicator consists of flow patterns visible on the soil surface or eroded into the soil, low vegetation bent over in the direction of flow, absence of leaf litter or small woody debris due to flowing water, and similar evidence that water flowed across the ground surface. C) indicators that the soil was saturated recently Indicato�C1: Hydrogen sulfide odor Category: Primary General Description: A hydrogen sulfide(rotten egg)odor within 12 (30 cm)of the soil surface. Indicator C3: Oxidized rhizospheres along living roots Category: Primary General Description: Presence of a layer containing 2 percent or more iron-oxide coatings or plaques on the surfaces of living roots and/or iron-oxide coatings or linings on soil pores immediately surrounding living roots within 12 in. (30 cm)of the soil surface. Indicator C4: Presence of reduced iron Category: Primary General Description: Presence of a layer containing reduced (ferrous) iron in the upper 12 in. (30 cm)of the soil profile, as indicated by a ferrous iron test or by the presence of a soil that changes color upon exposure to the air. Indicator C6: Recent iron reduction in tilled soils Category: Primary General Description: Presence of a layer containing 2 percent or more redox concentrations as pore linings or soft masses in the tilled surface layer of soils cultivated within the last two years. The layer containing redox concentrations must be within the tilled zone or within 12 in. (30 cm)of the soil surface, whichever is shallower. Indicator C7: Thin muck surface Category: Primary General Description: This indicator consists of a layer of muck 1 in. (2.5 cm)or less thick on the soil surface. Indicator C2: Dry-season water table Category: Secondary General Description: Visual observation of the water table between 12 and 24 in. ( 30 and 60 cm) below the surtace during the normal dry season or during a drier-than-normal year. Indicator C8: Crayfish burrows Category: Secondary General Description: Presence of crayfish burrows, as indicated by openings in soft ground up to 2 in. (5 cm) in diameter, often surrounded by chimney-.like mounds of excavated mud.
