A digital grid of the top of the McMurray 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 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 '-9999'). 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 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 GIS dataset depicts the surficial geology of NTS map area 84O south (point features). The data were created in geodatabase format and output for public distribution in shapefile format. The map was prepared by airphoto interpretation of 1:60 000-scale images flown in 1994. There was no ground-truthing.

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 present-day land surface. 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 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 resolution, based on information as recent as 2003.

This GIS dataset depicts the surficial geology of the NTS map area 84B Northeast (line features). The data are created in ArcInfo format and output for public distribution in Arc export (E00) and shapefile formats.

This GIS dataset depicts the surficial geology of the NTS map area 84M Northeast ( line features). The data are created in ArcInfo format and output for public distribution in Arc export (E00) and shapefile formats.

This GIS dataset depicts the surficial geology of the NTS map area 83P Southeast (polygon features). The data are created in ArcInfo format and output for public distribution in Arc export (E00) and shapefile formats.

This GIS dataset depicts the surficial geology of NTS map area 84O south (permafrost polygon features). The data were created in geodatabase format and output for public distribution in shapefile format. The map was prepared by airphoto interpretation of 1:60 000-scale images flown in 1994. There was no ground-truthing.
