Quaternary Evolution of the Prairie Creek Lake Basin, Daviess County, Indiana

Abstract

Broad, nearly level plains occupy large areas in the upland valleys adjacent to the White River in Daviess County, Indiana. These plains are underlain principally by lacustrine muds and fluviodeltaic sands that were deposited during the Woodfordian Age (late Wisconsinan), but a variety of associated sediments, including eolian sands and loess, alluvial sands and muds, paludal muds, and glacial and glaciolacustrine sediments of varying textures are also present. The sediments are arranged in a complex architecture reflecting facies relationships, normal stratigraphic superposition, and inset stratigraphic relationships that reflect the direct and indirect effects of glacial ice in the White River drainage basin.
