description Norrköpingsåsen Overview
Norrköpingsåsen is an esker, a ridge of sand and gravel deposited by meltwater from the Scandinavian Ice Sheet, on which Norrköping, Sweden, is situated. Its permeable glaciofluvial deposits allow water to infiltrate and be stored as groundwater, giving the formation local importance for water resources. It is part of the Quaternary landscape of Östergötland and illustrates how an urban area can be built on a glacial landform.
