To all that don’t know, Miami, Miami Beach ,Ft. Lauderdale Beach were originally SWAMPS!
I personally know that west of SR7/441 in the 1950s was still locally considered Everglades. Where the Dolphins play(?), I used to hunt and fish. 1957 waterskied in canal(same area)to the end at what is now Flamingo Road. Great place to shoot Garfish!
There is a very narrow Hardpan(coral/limestone ridge running South to North from the Keys to above Jupiter that is the lynch pin of the”South Florida” area. East was/is barrier islands, West is sand prairie or swamp, that are now communities!

I used to live a couple of blocks east of that narrow ridge, and went to school on the other side of it. There it was, the one and only hill in all of South Florida. (I didn’t know that it extended so far north and south; I thought it was localized in southern Palm Beach County.)
I suppose that all the white people in the region must live on that ridge, and all the black and Hispanic and “Caribbean-American” people must live everywhere else. So when the seas rise, South Florida will be nothing more than a long, extremely narrow peninsula filled with nothing but white people.
