The Gulf Coast Plains today lap over old existing mountain chains called the Ouachita Mountains and the southern toe of the Appalachian Mountains. Some of the roots of these mountains can be seen in southern Arkansas and northern Alabama. But these mountains did not form in the Gulf Coast Plain, they preceded the Gulf Coast Plain by many millions of years, the Ouachita being much older than the Appalachian.

Mountains don't form plains. Much of the Gulf Coast is silt washed down from the Missippi River and other lesser rivers that empty into the Gulf.

Would you be referring to the Appalachian Mountains? These old worn down mountains do extend to the Gulf Coastal Plain in Alabama but are not in the coastal plain itself.
There are no mountains in the coastal plains as the above poster has mentioned.
