Quaternary geology and bedrock subcrop of the Cold Lake to Ft. McMurray area, Alberta - Subcrop edge of the Viking Fm. - (1:250,000 scale gridded data)

A digital grid of the subcrop edge of the Viking Formation, originally modeled from borehole data and adjusted to present-day and paleo river erosion. Values in the grid correspond to areas where the unit is present (denoted by the number '25'), or where it is absent (denoted by the null value '-9999'). The grid is generated at a 250 m cell-size resolution, based on information as recent as 2003.
