This dataset has stratigraphic and lithological picks of the upper bedrock and Quaternary geological units in the Athabasca Oil Sands Area extending north from Cold Lake to the Fort McMurray region. The picks were compiled from the mid-1970s to 2006 to construct maps of the subsurface distribution, structure, topography and thickness of near-surface bedrock and Quaternary stratigraphic units. Alberta Geological Survey staff, as well as staff from industry and other government departments, interpreted the data.
