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

This GIS data set is a compilation of known kimberlite pipe locations for Alberta. The positions are generally known to +/- 500 m or better on the ground.

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.

The data represent the locations of thalwegs (paleo-channels) incised in the bedrock surface. 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.

The drift thickness map of the Pelican River area (NTS 83P) shows the variation in thickness of unconsolidated sediment lying between the bedrock surface and the present-day land surface, and complements the regional drift thickness map of Alberta (Pawlowicz and Fenton, 1995). The thickness of the drift varies from less than 20 metres in uplands, such as the Pelican Mountains, to a little over 260 metres in the Wiau Valley in the northeast part of the map area. The thickest drift fills the paleovalleys containing the major valleys: the Wiau Valley and the Leismer Valley in the northeast, and the north-trending Amesbury Valley in the central portion of the area.

All available bathymetry and related information for Lawrence Lake were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.
