Description

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 Alberta using previously published information from Alberta Geological Survey (AGS) maps and reports, as well as new data. The quality of this data has been assessed and then a quality-weighting approach was applied to the dataset prior to interpolation. The surface was modelled using a 500m x 500m grid cell spacing, and as such should not be used for local scale studies. This grid represents the surface portrayed in AGS Map 602, Bedrock Topography of Alberta, and this grid will continue to be updated as part of the Alberta Geological Framework project. Explanatory notes, references, and data sources appear on a supplementary page to accompany Map 602. These notes describe the distribution of...

Description

The drift thickness map of the Peerless Lake area (NTS 84B) shows the variation in thickness of unconsolidated sediment lying between the bedrock surface and the present-day land surface, and complements the Drift Thickness of Alberta map (Pawlowicz and Fenton, 1995). The thickness of the drift varies from locally less than 2 metres in Buffalo Head Hills to over 200 metres in the Loon River Lowland in the central part of the map area. Thick drift fills the major paleovalleys, which are the Muskwa Valley, the Red Earth Valley and Gods Valley. The drift is thinnest on the Peerless Lake Upland, the Utikuma Uplands and the Buffalo Head Hills Upland. In general the areas of thin drift correspond to areas where the bedrock topography is high. Exceptions are the hills composed of thick drift, such as the ones located south of Muskwa Lake and southwest of Peerless Lake. These features are likely hill-hole pairs produced by glaciotectonism with lakes occupying the source depressions (holes)....

Description

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 Wandering River plains. The elevation of the bedrock surface ranges from 360 metres above sea level (masl) in the Wabasca Plain to slightly more than 920 masl in the Pelican Mountains. Segments of three major buried valleys are present: the Wiau Valley and the Leismer Valley in the northeast, and the south to northwest-trending Amesbury Valley in the central portion of the area.
