The sub-Cretaceous unconformity is a major component of the three-dimensional geological model of Alberta.  This dataset is a two-and-a-half dimensional (2.5D) grid surface of the sub-Cretaceous unconformity elevation for the Lower Athabasca region of Alberta. The study area boundary covers NTS map sheets 73M, 74D, 83P and 83A.

To create this grid, stratigraphic picks of the sub-Cretaceous unconformity were geostatistically analyzed and interpolated to model the unconformity surface elevation.
