AbstractThe Champlain Sea was an inland arm of the Atlantic Ocean that invaded the St. Lawrence Lowland following retreat of the Laurentide Ice Sheet. This fieldtrip reviews a number of aspects of the deglacial landforms and deposits of the area, discusses the Champlain Sea deposits and reviews the societal implications of the deposits from a geotechnical and hydrogeological perspective. Day one of the two day trip is spent on the Vars - Wincehester esker which provides an opportunity to discuss esker and Champlain Sea deposits and to highlight the geotechnical and hydrogeological issues associated with these deposits. Day two of the trip visits the Cantley quarry and discusses the evidence for and against subglacial meltwater erosion for the sculpted forms at the site.
