Structure Top of the Haynes Aquifer, Alberta (Gridded data, ASCII format)

This is a 1000 m cell-sized raster grid dataset of the top of the sandstone of the Haynes member of the Paskapoo Formation. We mapped the sandstone using 3-D geostatistical modelling algorithms from data derived from sand calculations of 25 m thick slice intervals of the Paskapoo Formation. We selected the >55% sand isovalue to define sandstone, based on the results of mini-models that show vertical hydraulic connections being established if sand abundance is 55% or greater. This grid represents the upper surface of that three-dimensional body defined by the >55% sand threshold value. Alberta Geological Survey Bulletin 66 provides a detailed description of how the unit was defined. The dataset is in ESRI ASCII grid format.
