Index Map of Triassic Rocks (GIS data, line features)

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 16 of the Atlas, Triassic Strata of the Western Canada Sedimentary Basin, Figure 1, Index Map of Triassic Rocks. 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.
