Environment description: Very swampy area in a wetland area associated with the edges of Basin Creek. Soils: The underlying geology of this area is classified as Undifferentiated Sediments, of Pleistocene/Holocene origin. This geology is characterized by undifferentiated Quaternary Sediments - much of Florida's surface is covered by a varying thickness of undifferentiated sediments consisting of siliciclastics, organics and freshwater carbonates. Where these sediments exceed 6.1 meters thick, they were mapped as discrete units. In an effort to subdivide the undifferentiated sediments, those sediments occurring in flood plains were mapped as alluvial and flood plain deposits. Sediments showing surficial expression of beach ridges and dunes were mapped separately as were the sediments composing Trail Ridge. The subdivisions of the Undifferentiated Quaternary Sediments are not lithostratigraphic units but are utilized in order to facilitate a better understanding of the State's geology. The siliciclastics are light gray, tan, brown to black, unconsolidated to poorly consolidated, clean to clayey, silty, unfossiliferous, variably organic-bearing sands to blue green to olive green, poorly to moderately consolidated, sandy, silty clays. Gravel is occasionally present in the panhandle. Organics occur as plant debris, roots, disseminated organic matrix and beds of peat. Freshwater carbonates, often referred to as marls in the literature, are scattered over much of the State. (Source: USGS Florida Geologic Map Data). The surface soil profile of this area is primarily Dorovan-Pamlico series association. The Dorovan series consists of very deep, very poorly drained, moderately permeable soils on densely forested flood plains, hardwood swamps and Southern Coastal Plain Major Land Resource Areas. They were formed in highly decomposed acid-organic materials. Slopes are less than 1 percent. The organic material ranges from 1.3-2.1 meters thick. Reaction is extremely acid to very strongly acid in the organic layers and very strongly acid or strongly acid in the mineral layers. The Pamlico series consists of very poorly drained soils that formed in decomposed organic material underlain by dominantly sandy sediment. The soils are on nearly level flood plains, bays, and depressions of the Coastal Plain. Slopes are less than 1 percent. Pamlico soils have 0.4-1.3 meters of organic material over dominantly sandy sediments. Reaction is extremely in the organic layers and ranges from extremely acid to strongly acid in the underlying mineral layers. (Source: USDA-NRCS Official Soil Series Descriptions).
