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

A digital grid of the subcrop edge of the Second White Specks Formation and bedrock units above, such as the Wapiti Formatioin, 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, 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.
