A digital grid of the subcrop edge of the McMurray Formation, originally modeled from borehole data and adjusted to present-day and paleo river erosion. Values in the grid correspond to areas where the unit is present (denoted by the number '6'), or where it is absent (denoted by the null value...

A digital grid of the top of the Clearwater Formation, originally modeled from borehole data and adjusted to present-day and paleo river erosion. The grid is generated at a 250 m cell-size resolution, based on information as recent as 2003.

A digital grid of the top of the Viking Formation, originally modeled from borehole data and adjusted to present-day and paleo river erosion. The grid is generated at a 250 m cell-size resolution, based on information as recent as 2003.

A digital grid of the top of the Empress Fm. Unit 2 silt and clay, (the middle unit in the Empress Formation), where present, or the topography of the surrounding landscape, where Unit 2 is absent. The unit is originally modeled from borehole data and adjusted to the bedrock surface, the surface...

A digital grid of the top of the Empress Fm. Unit 1 sand and gravel, (the lowermost unit in the Empress Formation), where present, or the topography of the surrounding landscape, where Unit 1 is absent. The unit is originally modeled from borehole data and adjusted to the bedrock surface and...

A digital grid of the subcrop edge of the Joli Fou Formation, originally modeled from borehole data and adjusted to present-day and paleo river erosion.

A digital grid of the subcrop edge of the Second White Specks Formation and bedrock units above, such as the Wapiti Formatioin, originally modeled from borehole data and adjusted to present-day and paleo river erosion. Values in the grid correspond to areas where the unit is present, or where it...

This grid dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the net-to-gross sandstone ratio distribution within the Paskapoo Formation - Upper Composite Slice of the Sylvan Lake...

A digital grid of the subcrop edge of the Viking Formation, originally modeled from borehole data and adjusted to present-day and paleo river erosion. Values in the grid correspond to areas where the unit is present (denoted by the number '25'), or where it is absent (denoted by the null value...

This polygon dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. This dataset provides the areal distribution of greater than or equal to 0.60 net-to-gross sandstone values for the Paskapoo...

A digital grid of the top of the Empress Formation where present, or the topography of the surrounding landscape, where the formation is absent. This includes the units 1 to 3 of the Empress Formation in buried valleys, as well as undifferentiated Empress interfluve sediments resting on the...

This GIS dataset illustrates the areal extent (surface and subsurface) of the Sunchild aquifer. It is in ESRI shapefile format.

A digital grid of the top of the sand and gravel deposits that lie on the interflueve benches between major bedrock valleys. The unit is originally modeled from borehole data and adjusted to the bedrock surface and the present-day land surface. The grid is generated at a 250 m cell-size...

This is a polygon dataset illustrating the areal extent (surface and subsurface) of the Haynes aquifer. It is in ESRI shapefile format.

This is a 1000 m cell-sized raster dataset of the upper surface of the Sunchild Aquifer, modelled from the >55% sand point data derived by depth-slice analysis of well-log data. Alberta Geological Survey Bulletin 66 provides details on this grid dataset. The dataset is in ESRI ASCII grid format.
