A typical landscape of the Piledriver soil series (Aquic Cryofluvents). The Piledriver series consists of very deep, somewhat poorly drained, moderately permeable soils on floodplains. They formed in stratified silty and sandy alluvium overlying sand and gravel. The climate is subarctic continental with long, cold winters and short, warm summers. Slopes range from 0 to 2 percent.
Runoff is slow. Saturated hydraulic conductivity is moderately high to high in the upper part and high to very high in underlying material. These soils are subject to rare or occasional flooding. A water table is present at a depth of 3 to 6 feet for some period in most summers, allowing capillary rise of water into the soil profile. They have low chroma redoximorphic depletions from 3 to 33 inches and irregular decrease in organic carbon with depth.
The series is of minor extent in the Interior Alaska Lowlands. Most areas are in native forest consisting of white spruce, cottonwood and quaking aspen with alder shrubs.
