This map highlights an interesting geographic feature I’ve never been aware, which is a distinct line running down the east coast of the USA, from Philadelphia, through Wilmington and Fayetteville, all the way to Florida.
Looking at another map, it does seem like a real feature, with a small but abrupt increase in hilliness as we travel west from the coast. Does anyone know if this geographical feature has a name?
- hervature 5y agoI think you are talking about the Piedmont plateau leading into the Appalachian mountains but I'm not sure.
- akamaka 5y agoThanks, it is the eastern edge of the Piedmont I was looking at.

- akamaka 5y agoThank you, that is exactly it! Goes off to binge read Wikipedia
- eesmith 5y agoThe part in central Florida is the Lake Wales Ridge, remnants of 1M+ year old islands. https://en.wikipedia.org/wiki/Lake_Wales_Ridge https://en.wikipedia.org/wiki/Lake_Wales_Ridge . The combination of Florida heat and fast-draining sandy soil makes it the closest thing Florida has to a desert. If I read things correctly, that line continuing up through Georgia is the Cypresshead Formation.
