Geology[edit]
The Western Canadian Sedimentary Basin is a foreland basin, formed by the downflexing of the North American Plate due to loading by the Rocky Mountains fold and thrust belt during the Cretaceous. It lies above a Devonian rift sequence, formed in the Elk Point Rift, and a Permian to Jurassic post-rift sequence.[1]
