Calgary-Lethbridge Corridor Hydrostratigraphic Model - Top of the Paskapoo / Porcupine Hills Hydrostratigraphic Unit, Southwestern Alberta (gridded data, ASCII format)

This dataset is part of the 3D hydrostratigraphic model of the Calgary-Lethbridge Corridor (CLC), southwestern Alberta. It represents the structure top of the Paskapoo / Porcupine Hills hydrostratigraphic unit (HSU), which is the bedrock topography surface in the CLC where the HSU is present. 
Bedrock units included in the CLC model are derived from the Geological Framework of Alberta, a regional geological model of the province. The extent of the top of the Paskapoo / Porcupine Hills 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.
