Triassic Spearfish Lower Watrous and Lower Amaranth Isopach (GIS data, line features)

Author(s) Kent, D.M. Christopher, J.E. Date 2008-01-22

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 27 of the Atlas, Geological History of the Williston Basin and Sweetgrass Arch, Figure 14, Triassic Spearfish Lower Watrous and Lower Amaranth Isopach. 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.
