This dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of the Lea Park Formation in the Sylvan Lake sub-basin. Bedrock units included in the Sylvan Lake sub-basin model are derived from the Geological Framework of Alberta, a regional geological model of the province. The Top of Lea Park Formation, provided by the Geological Framework of Alberta, was clipped to the Sylvan Lake sub-basin model domain for integration into a multi-layer hydrostratigraphic model. This dataset supplements Alberta Geological Survey (AGS) Open File Report 2014-10, which includes a full description of the methodology used to produce this grid.
