SURVEY OF QUATERNARY GLACIOLACUSTRINE SEDIMENTS OF NORTHWESTERN VERMONT

Sediment sequences are integral in determining paleo-environmental changes through time. By mapping and analyzing these deposits, we have reconstructed an environmental history pertaining to the setting under which these sediments were deposited. By analyzing the surficial packages, we have determined that the area of study contains a delta formed during the Coveville Stage of Glacial Lake Vermont. This analysis is based on our newly created surficial geological map of an area just west of Johnson, Vermont. Through the application of spatial analysis techniques using GIS software a set of maps were produced to describe current surficial deposits in the area. From these maps, we constrain the present elevation (above sea level) and lateral distribution of this Quaternary Glacial Lake Vermont, Coveville Stage marginal delta.
