This grid dataset is part of the 3D hydrostratigraphic model of the Calgary-Lethbridge Corridor (CLC), southwestern Alberta. The grid is a rendering of the thickness and distribution of sediment overlying the CLC bedrock topography.
The thickness and distribution of sediments overlying the bedrock surface in the CLC is highly varied, ranging from less than 1 m to as much as 160 m. These sediments include Neogene fluvial deposits, glacigenic materials deposited during Quaternary glaciation, as well as postglacial sediments.
This dataset supplements Alberta Geological Survey (AGS) Report 91 and INF 150, which include a full description of the process used to produce the sediment thickness grid.
