Honey Creek Member, Holocene alluvium, DeForest Formation
This paper describes the type locality and type section for the Honey Creek Member, a stratigraphic unit first recognized in the Honey Creek drainage in southeastern Nebraska. The alluvial chronology for Honey Creek basin is similar to the regional chronology of streams in the Midwest, and all of the formal members of the DeForest Formation occur in the basin. However, the lithology of one unit, the Honey Creek Member, does not correlate with any of the formally recognized members of the DeForest Formation. The Honey Creek Member is composed of grayish brown silt loam overbank facies coarsening downward to a gravelly loam channel facies with prominent, large-scale cross-bedding. At its type locality, aggradation of the Honey Creek Member occurred from ca. 3700 14C yrs. B.P. to ca. 600 14C yrs. B.P. Paleochannels preserved within the unit suggest that aggradation was interrupted by at least two episodes of channel entrenchment and filling. The Honey Creek Member is significant because it has been identified within many basins across the eastern Plains. Recognition and detailed mapping of this unit facilitates our understanding of fluvial behavior during the late Holocene.
