The Canadian Rocky Mountain foreland thrust and fold belt is a northeastward tapering deformational belt consisting of Mesoproterozoic, Paleozoic, and Mesozoic strata. The Lewis thrust sheet is one of the major structures of the foreland thrust and fold belt extending over 280 mi (450 km) from Mount Kidd near Calgary, AB in the Southeast Canadian Cordillera to Steamboat Mountain, located west ...

The Rocky Mountains were formed by a series of events, the last of which is the Laramide Orogeny. [35] One of the outstanding features of the Rocky Mountains is the distance of the range from a subducting plate; this has led to the theory that the Laramide Orogeny took place when the Farallon plate subducted at a low angle, causing uplift far ...
