A little-known fact: the route crosses the 100th meridian, the historical dividing line between the arid West and the humid East. This geographic transition is visible in the changing landscape from sagebrush to cornfields.

The journey begins in the Black Hills, a region of granite peaks and pine forests. As you descend east, the land flattens into the Great Plains, punctuated by the Missouri River near Chamberlain. South Dakota's signs of prairie dog towns and buffalo herds give way to Iowa's rolling hills and limestone bluffs.
