This dataset is part of the 3D hydrostratigraphic model of the Calgary-Lethbridge Corridor (CLC), southwestern Alberta. It represents the structure top of hydrostratigraphic unit (HSU) S2, which contains coarse-grained glaciofluvial and fluvial sediments that are distributed throughout the modern drainage system. HSU S2 overlies HSU C in the Neogene-Quaternary succession of the CLC and is the top boundary of the model domain.
This dataset supplements Alberta Geological Survey (AGS) Report 91, which includes a full description of steps taken to produce the structure grid.
