Fascinating and Intriguing Facts About US Geography We Never Learned Until Now

In the vast expanse west of the Mississippi River, most contiguous U.S. state borders are characterized by straight lines or follow natural features like rivers. However, there’s one notable exception: the border between Idaho and Montana, specifically along the Bitterroot Mountain Range.

This unique deviation from the norm adds to the mystique of the Western landscape, showcasing the challenges and intricacies involved in defining state borders.
