Do people call it 'pluff mud' anywhere besides South Carolina?

Question

I've had to explain what pluff mud is to quite a few tourists lately, and it never occurred to me that it might be a pure colloquialism used nowhere outside the lowcountry. Is it? It seems like marsh mud would be pretty much the same throughout the southeast.

Answer 1

I'm from North Carolina (the Piedmont, though), and I've never heard that expression.

Answer 2

Nope, it must be a colloquialism.  I live in SC.  Not the low country though.  I never have heard it called "pluff mud"  Even though it's befitting I suppose.

Answer 3

I've never heard that term here in Ohio.

Answer 4

I am a geologist who studies sedimentary rocks, especially coal, which grows in swamps.  I have never heard the term, although I spent many years in North Carolina.

Answer 5

I am in Washington state and have never heard that. Must be your guys' thing.
