Burton LUP - 7Ad Glacial Till Over Sandstone

7Ad Glacial Till Over Sandstone

This hydrologic setting is characterized by low topography and relatively flat-lying, fractured sandstones which are covered by varing thicknesses of glacial till. The till is principally unsorted deposits which may be interbedded with loess or localized deposits of sand and gravel. Although ground water occurs in both the glacial deposits and in the intersecting bedrock fractures, the bedrock is typically the principal aquifer. The glacial till serves as a source of recharge to the underlying bedrock. Although precipitation is abundant in most of the region, recharge is moderate because of the glacial tills typically weather to clay loam. Depth to water is extremely variable, depending in part on the thickness of the glacial till, but averages around 40 feet.
