A digital grid of the top of the Grand Rapids 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.

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 structure top of the Paskapoo Formation, which is the bedrock surface in the Sylvan Lake sub-basin. The Paskapoo...

This is a polygon dataset illustrating the areal extent (surface and subsurface) of the Haynes 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...

Sand bodies within the Sunchild aquifer subcrop over most of its extent, and because overlying Neogene sediment is relatively thin in the western part of the Paskapoo Formation, the unit expresses itself as the present-day topography. Constructing the Sunchild aquifer-thickness map was somewhat...

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...

This dataset is a grid of the thickness of the Haynes aquifer within the Paskapoo Formation. The Haynes aquifer is a regionally extensive body of sand that lies in the bottom part of the Paskapoo Formation. The isopach was created from the modelled results of the average sandiness of 25 m thick...

A digital grid of the top of the Empress Fm. Unit 3 sand and gravel, (the uppermost unit in the Empress Formation), where present, or the topography of the surrounding landscape, where Unit 3 is absent. The unit is originally modeled from borehole data and adjusted to the bedrock surface, the...

A digital grid of the subcrop edge of the Base of Fish Scales horizon, 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 '15'), or where it is absent (denoted by the...

A digital grid of the top of the Joil Fou 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.

This 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 structure top of hydrostratigraphic unit (HSU) S1, which contains coarse-grained material lying directly on bedrock and...

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.

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 structure top of the Paskapoo Formation - Lower Composite Slice of the Sylvan Lake sub-basin. The Paskapoo Formation...

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 Second White Specks 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 elevation model derived from the Federal DEM (76m resolution) and resampled to a 250 m cell-size resolution.

A digital grid of the subcrop edge of the Clearwater 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 '8'), 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 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...

This 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 structure top of the Wapiti Formation in the Sylvan Lake sub-basin. Bedrock units included in the Sylvan Lake sub-basin...
