This dataset is part of the 3D hydrostratigraphic model of the Calgary-Lethbridge Corridor (CLC), southwestern Alberta. It represents the structure top of the Horseshoe Canyon / St. Mary River 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 Horseshoe Canyon / St. Mary River 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.
