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.
