The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 24 of the Atlas, Uppermost Cretaceous and Tertiary Strata of the Western Canada Sedimentary Basin, Figure 2, Uppermost Cretaceous and Tertiary-Index Map. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

The dataset includes subsurface stratigraphic picks for the top of the Foremost Formation (Belly River Group) in the Alberta Plains (Townships 1 to 52, Ranges 1W4 to 5W5) made from downhole wireline geophysical well logs. The top of the Foremost was picked at the base of a continuous sandstone or siltstone bed (low-gamma-ray) of variable thickness overlying the Taber coal zone. Well data were screened to detect errors resulting from deviated wells, as well as incorrect ground and kelly bushing elevation data. We used statistical methods to identify local and regional statistical outliers, which were examined individually.

This polygon dataset represents meltwater deltas and fans depicted in AGS Map 207, 'Quaternary Geology, Southern Alberta'.

This is a polygon dataset illustrating the areal extent (surface and subsurface) of the Haynes aquifer. It is in ESRI shapefile format.

Base waterbody polygon arcs are feature type, source and capture date attributed arcs that make up the boundaries of base waterbody polygons in the Base Features Hydrography geospatial dataset. These arcs were collected from conversion processes of 1:20 000, 1:50 000 and AVI Provincial mapping datasets and 1:50 000 National Topographic Data Base (NTDB).

All available bathymetry and related information for Cache 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.

This digital data release includes Rock Eval and total organic carbon results of selected samples for analyses of shale gas, oil and liquids. The strata evaluated include the: - basal Banff Formation, - Colorado Group, - Duvernay Formation, - Exshaw Formation, - Montney Formation, - Muskwa Formation, - Nordegg Member, and - Rierdon Formation.

The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 13 of the Atlas, Devonian Wabamun Group of the Western Canada Sedimentary Basin, Figure 9, Net Dolomite Isopach - Lower Stettler Fm. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 10 of the Atlas, Devonian Elk Point Group of the Western Canada Sedimentary Basin, Figure 6, Distribution of Lower Middle Devonian, Headless Equivalents. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

The Cold Lake oil sands area - Township 56 to 69, Range 1 to 11, west of the 4th Meridian, falls within the Lower Athabasca Regional Plan (LARP). As part of Alberta's Land-use Framework, LARP was developed in 2012 to set the stage for robust growth, vibrant communities and a healthy environment within the region. One of its implementation objectives is to balance the economic development of oil sands and impacts on the ecosystem and environment. This is to be achieved through an enhanced science-based monitoring for improved characterization of the environment and to collect the information necessary to understand …
