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 '-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 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.

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 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.

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 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 null value '-9999'). The grid is generated at a 250 m cell-size resolution, based on information as recent as 2003.

The bedrock topography map of the Peerless Lake area (NTS 84B) shows the elevation of the bedrock surface. In general, the topography of the land surface reflects the bedrock topography. Thus, bedrock highs underlie the Buffalo Head Hills Upland, Peerless Lake Upland and Utikuma Uplands. Major buried valleys lie within the Loon River Lowland in the west-central part and within the Wabasca Lowlands in the south and northeast parts of the map area. The elevation of the bedrock surface ranges from 780 metres above sea level (masl) in the Buffalo Head Hills to 300 masl in the Loon River Lowland. Segments of three major buried valleys are present: the Muskwa Valley in the south, the Red Earth Valley in the Loon River Lowland and Gods Valley in the northeast. The exact shape of these bedrock valleys and their relationships in the areas where they appear to merge is uncertain as a consequence of the scarcity of relevant drillholes. The Muskwa Valley trends westward towards Lubicon Lake and approximately corresponds with the southern part of the Misaw Channel of Ceroici and part of the L'Hirondelle Channel of Ceroici and Borneuf. The eastern extent of the Muskwa Valley also corresponds with a bedrock low in the northeast corner of the Lesser Slave Lake map area (NTS 83O). The Red Earth Valley partly corresponds to the northerly trending segment of the Misaw Channel of Ceroici, although in the northern part of Loon River Lowland the Red Earth Valley trends north-northeasterly. In the northern part of the Loon River Lowland, abrupt changes in the elevation of stratigraphic markers appear to define a northeasterly trending graben-like structure, which suggests the trend of the Red Earth Valley is partly controlled by bedrock structure. The lowest elevation along the Red Earth Valley is near the town of Red Earth Creek.

A digital grid of the top of the bedrock surface, originally modeled from borehole data and adjusted to present-day 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 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.
