WOW that explains a lot. I never new Florida had an escarpment!
Like most things in Florida its old and worn down but its there and explains what we have all noticed and commented on.
Dirt above I10 is different than below. Below I 10 is very sandy. above is more clay and loam. Now I know why. And why the Highest Point is Florida is just below the GA state line.
