The Fall Line is a cool thing in the Southeast United States, where the land has a stark transition from soil types. The geography also changes from Piedmont (rolling hills, deciduous trees) to coastal plain (more flat, more pine trees) because of this. I’ve observed this in real life, it kind of splits North Carolina (and all the other states with it) into distinct sections, like the east vs the central part. It’s especially stark in Georgia, where the large majority of the population lives north of the line.

It also has determined where many large cities are. Richmond, Philadelphia, Wilmington, Raleigh, Columbia, Baltimore, Washington DC, Fredericksburg, Rocky Mount, Fayetteville, Augusta, Macon, Montgomery, and Tuscaloosa are all on the Fall Line. One reason for this is because there are a lot of waterfalls on the line as it transitions, they built the cities on the coastal side (before the waterfalls) so ships could still get there.

I’m gonna try to make one post every day about something I’m interested in, like this.
