Thickness of Glacial Sediments in Connecticut and the Long Island Sound Basin Polygon

The Thickness of Glacial Sediments in Connecticut and the Long Island Sound Basin layer contains interpretive polygon data representing the thickness of glacial sediments in Connecticut and the Long Island Sound Basin. Compiled as part of the Quaternary Geologic Map of Connecticut and Long Island Sound Basin, Stone and others (1998, 2005). Includes thickness of glacial sediments in 50 foot (0-50, 50-100) and then 100 foot (100-200, 200-300, etc) intervals. Data derived from original mapping at 1:80,000 scale for the Long Island Sound basin and at 1:125,000 scale on the land in Connecticut. The data are NOT recommended for use at higher resolution scales.
