The country's newest national park used to be called Congaree Swamp National Monument, and it doesn't take long to notice the knobby-kneed Cyprus, black water and musty air of the bottomlands.
But, park ranger Fran Rametta says the Congaree National Park <http://www.nps.gov/cosw/>
; is much more than that.
Its 22,000 acres contain the only old-growth flood-plain forest left in the US. They're home to some of the largest trees along the East Coast. One of the trees in the park is a state-record loblolly pine that measures 16 feet around.
