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) C, which contains fine-grained materials, typically diamicton and/or till and glaciolacustrine deposits (clay) directly overlying bedrock or coarse-grained sediments of HSU S1 in the Neogene-Quaternary succession of the CLC.
This dataset supplements Alberta Geological Survey (AGS) Report 91, which includes a full description of steps taken to produce the structure grid.
