AbstractThe Virden area study is part of the Southern Prairies NATMAP Project. In general, the area is flat and characterized by thick drift. Surface materials consist of till, clay, silt, sand, and gravel. The thickness of drift varies from as little as 1 m, where a single till sheet overlies bedrock, to more than 100 m in buried valleys and where multiple till units are present. During the last glaciation, ice movement was generally towards the southeast. During ice retreat, several glacial lakes formed at the margin of the retreating ice, and a number of catastrophic floods cut spillways and deposited extensive sheets of sand and gravel. The report package includes extensive databases of field-collected information, borehole records, and aggregate data. These databases have been used to produce a wide variety of derived products which include, observed surface-material maps, drift-thickness maps etc. These have a number of uses such as showing potential aggregate deposits, making it possible to map aquifers prone to contamination, etc. The package includes innovative software for viewing maps and databases.
