Since that time, there have been several attempts to develop regional hydric soil ©2001 CRC Press LLC Figure 8 A generalized soil profile. Actual horizons represent a continuum and will not appear this distinct in the field. field indicators (New England Hydric Soils Technical Committee, 1998). Recognizing and applying these field indicators will enable the wetland scientist to field confirm or refute the hydric soil criterion.

Horizons can be distinguished based upon color, texture, and composition (Environmental Laboratory, 1987). However, the soil horizon is essentially a continuum and there is no clear distinction between one horizon and another. Soils typically have four major horizons: an organic layer (O) and three mineral layers (A, B, and C); see Figure 8. The O horizon is the surface layer and is composed of fresh or partially decomposed organic material. The A horizon is characterized by an accumulation of organic matter and the loss of clay, iron, and aluminum.

Emphasis should be placed on comparing and contrasting individual sources: that is, comparing and corroborating the results from USGS to NWI to the Soil Survey, being sure to consider the years each source was initially produced. S. Department of Agriculture Natural Resources Conservation Service indicates hydric soils in the western and southern sections of the site (Figure 3). Therefore, the interpreter can be reasonably confident that wetlands, and most likely forested wetlands, exist at the site.
