SOIL SURVEY

-55-BC2 Map Unit (Orthic and Rego Gleysols )This map unit is characterized by poorly drained, medium textured soils wit hthin organic surface horizons . These soils have developed on alluvium . The texturesare generally silt to silt loam and coarse fragment contents are usually less than 5% .Mottles are present throughout the pedon . In oxbow areas, some submerged soils ma ybe included within this map unit concept .Table 9 . Brief description of the pedon chosen to characterize the BC 2 map unit .HorizonDepth(cm )Moist ColorEst .

These soils generally occur adjacen tto stream channels and may have a variable thickness of medium textured material sdeposited by recent flooding overlying the coarse textured materials . Mottles ar epresent to the soil surface .
