These are organiclayers with greater than 17% organic carbon content .
Soil Map Unit 4These poorly and very poorly drained soils are usuallyassociated with groundwater discharge and a high water table in basinareas and stream channels . The organic surface horizons contain 60 to70 percent organic matter which is mixed with alluvial sediment .Classification :These soils are classified as Rego Gleysols and have Oh,Cghorizon sequences in their profiles .The soils are often layered in acumulic manner due to burying of former soil surfaces by volcanic ashand alluvial deposits .Associated Map Units :Few map units are associated directly with Map Unit 4 althoughsome of the soils of Map Unit 4 may tend toward the peaty nature of MapUnit 5 . The soils of Map Units 1 and 3 often border the Map Unit 4areas .Vegetation :Plant communities are generally dominated by Carex nigricansalthough there are a few areas with mixed herbaceous communities .Pedon Description :Described by : L .
