Grande Prairie–Valleyview Area Hydrostratigraphic Model - Thickness of Hydrostratigraphic Subunit HSU1-Low Within the Paleogene–Quaternary Succession (gridded data, ASCII format)

This grid dataset is part of the 3D hydrostratigraphic model of the Grande Prairie–Valleyview area in northwestern Alberta. It represents the thickness of hydrostratigraphic subunit HSU1-low  which comprises basal coarse-grained, typically fluvial sediments directly overlying bedrock within buried valleys and on adjacent lower benches (i.e., planation surfaces no. 4 and 3). The dataset supplements AGS Report 102 which provides detailed information on the shallow stratigraphy and hydrogeology of the Grande Prairie–Valleyview area, and the steps taken to create the hydrostratigraphic model.
