    The North American Cordillera is the North American portion of the American Cordillera which is a mountain chain along the western side of the North American Cordillera covers an extensive area of mountain ranges, intermontane basins, and plateaus in western North America, including much of the territory west of the Great is also sometimes called the Western Cordillera Countries: United States, Canada and Mexico. The northern Paradox Basin evolved during the Late Pennsylvanian–Permian as an immobile foreland basin, the result of flexural subsidence in the footwall of the growing Uncompahgre Ancestral Rocky Mountain thick‐skinned by:

    During Late Cretaceous time a broad north-trending epicontinental sea covered much of the western interior of North America and extended from the Gulf of Mexico to the Arctic Ocean. The sea was bounded on the west by a narrow, unstable, and constantly rising cordillera which extended from Central America to Alaska and which separated the sea from Pacific oceanic waters.

Get this from a library. Stratigraphy of the Rocky Mountain Group in the southeastern Cordillera of Canada. [Donald Kring Norris]. Cordillera. The Cordillera is a complex region with three distinct mountain ranges: the Rocky Mountains in the east, the Coast Range (California Borderland) and Klamath Mountains on the west coast, and the Sierra Nevada and Cascade Mountain ranges just inland from the west coast.

The lower Rocky Mountain Supergroup of Pennsylvanian age contains five formations which in ascending order are: Todhunter, Tyrwhitt, Storelk, Tobermory and Kananaskis. All except the Kananaskis are new formations that are equivalent to the Tunnel Mountain Formation.

The Todhunter, Tyrwhitt and Tobermory consist mainly of brown weathering, dolomitic and quartzitic, very fine- to fine-grained.

This account summarizes the geology of the eastern Canadian Cordillera and includes the Rocky Mountains proper, southern Rocky Mountain Trench, Columbia Mountains, eastern Mackenzie Mountains, Franklin Mountains, and Richardson Mountains (Physiographic Regions of Canada, G.S.C.

Map A).These mountains occupy portions of western Alberta, eastern British Columbia, eastern. An unconformity is observed between Banff and the Rundle Group in outcrop.

The Banff Formation is equivalent to the Lodgepole Formation in Montana. It can be correlated with the Besa River Formation in north-eastern British Columbia. In the southeastern Rocky Mountains, part of the formation passes laterally into the Pekisko Formation.
