This GIS dataset depicts a geostatistical model of the thickness of sediment overlying bedrock in Alberta. The sediment thickness surface was generated to assist the construction of a new geological framework for Alberta. The surface was derived by subtracting the bedrock topography of Alberta...

This polygon dataset represents those parts of the ground surface modified by lake and stream erosion and deposition, as well as stagnation moraines covered by lacustrine sediment, as depicted in AGS Map 207, 'Quaternary Geology, Southern Alberta' (stippled and cross-hatched areas).
