The north-eastern part of the Roman Empire was formed by only one river: the Danube. The whole of the northern boundary of the Roman Empire was demarcated mostly by two rivers: the Danube and the Rhine. The latter marked the north-western frontier.
The Western Cordillera was formed primarily due to the tectonic activity associated with the collision of the North American Plate with the Pacific Plate and other smaller plates. This collision, which began around 200 million years ago, led to the uplift and folding of sedimentary rocks, creating the mountain ranges we see today, including the Rockies and the Sierra Nevada. Additionally, volcanic activity and erosion have shaped its current landscape over millions of years.
The mountain range that formed the western boundary of the original states was the Appalachian Mountains. The mountains also extend into southeastern Canada.
