Description
PRE-WISCONSIN_GLACIAL_LIMIT_IN.shp is a line shapefile that shows the extent of glaciation in Indiana as delineated by mapped glacial deposits of various types and ages at a scale of 1:500,000. The mapped units include Pleistocene sediments of glacial origin that are interpreted to have been deposited during multiple episodes of continental glaciation by the North American Laurentide ice sheet. The term pre-Wisconsin is meant to distinguish this glacial limit from that represented in a companion data set [WISCONSIN_GLACIAL_LIMIT_IN: Extent of Wisconsin Glaciation in Indiana (Indiana Geological Survey, 1:500,000, Line Shapefile)] that represents the (later or younger) limit of Wisconsin glaciation in Indiana.
