This dataset is part of the 3D hydrostratigraphic model of the Calgary-Lethbridge Corridor (CLC), southwestern Alberta. It represents the structure top of the Battle hydrostratigraphic unit (HSU) in the CLC. Bedrock units included in the CLC model are derived from the Geological Framework of Alberta, a regional geological model of the province. The top of the Battle HSU, provided by the Geological Framework of Alberta, was clipped to the CLC model domain for integration into a multi-layer hydrostratigraphic model.
Alberta Geological Survey (AGS) Report 91 includes a full description of the process used to produce this structure grid.
