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 data set is an updated, GIS version of part of the Alberta Geological Survey's published Map No. 226, which in turn is a regional synthesis of various published and unpublished maps. The data represent the locations of thalwegs (paleo-channels) incised in the bedrock surface.

The bedrock topography of Alberta is the surface of the top of Upper Cretaceous and Paleogene bedrock, and reveals geomorphic features created by Paleogene to Recent river systems and Quaternary glaciation. This dataset consists of previously published information from Alberta Geological Survey...

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 GIS dataset depicts the locations of thalwegs (paleo-channels) incised in the bedrock surface of NTS map area 84L ( line features). The data are created in ArcInfo format and output for public distribution in Arc export (E00) and shapefile formats.

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 GIS dataset depicts the structural bedrock top surface in the Edmonton-Calgary Corridor based on water-well litholog data, including bedrock outcrop locations. We sourced the well data from an internal Edmonton-Calgary Corridor geological mapping database. This surface provides a geological...

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...

The data represent the locations of thalwegs (paleo-channels) incised in the bedrock surface. Segments of three major buried valleys are present: the Muskwa Valley, the Red Earth Valley and Gods Valley in the northeastern portion of the area.

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...

The bedrock topography of Alberta is the surface of the top of Upper Cretaceous and Paleogene bedrock, and reveals geomorphic features created by Paleogene to Recent river systems and Quaternary glaciation. This grid is a computer-generated geostatistical model of the bedrock topography of...

The bedrock topography map of the Pelican River area (NTS 83P) shows the elevation of the bedrock surface. In general, the surface topography reflects the bedrock topography: bedrock highs underlie the Pelican, Amadou and May Hills highlands, and the buried valleys lie within the Wabasca and...

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 GIS dataset depicts the result of a geostatistical model of the bedrock topography in Alberta. This model is based on water-well litholog data, stratigraphic picks made on oil and gas petrophysical logs, data derived from digitized contour interpretations on bedrock topography maps,...
