KEY WEST -- Research divers and marine archaeologists expect to find shells, rocks and remnants of shipwrecks when they excavate areas of the ocean bottom.
But pine cones, tree branches and charred limbs -- thought to be about 8,400 years old -- were an unexpected and intriguing treasure awaiting archaeologist Corey Malcom, who spent much of the summer underwater in search of the remains of the Henrietta Marie, a British slave ship that sank 35 miles off Key West in 1700.
In August, Malcom, who is director of archaeology at the Mel Fisher Maritime Museum, was joined underwater by George Robb, founder of RPM Nautical Foundation and financial supporter of the Mel Fisher Maritime Heritage Society.
Robb was diving in about 40 feet of water as the search for the remaining cannons and other parts of the Henrietta Marie continued. The divers had previously surveyed various sites with electronic equipment able to locate objects that lie covered in sand on the ocean floor.

As RPM and museum divers checked out several "hits" that came from the equipment, they were particularly interested in one that was strong and a bit unusual. Upon first entering the water, nothing but sand was visible to them, so Malcom received permission from the Florida Keys National Marine Sanctuary to begin excavating the area. Previous permits only allowed surveying and examination.
Divers cleared a 2-by-3-meter area on the ocean floor and carefully began sifting through a thick mud that replaces sand underneath the water. About 10 inches down, they found a few small, glass beads that led them to believe they were close to more Henrietta Marie ruins, as hundreds of similar glass beads have been found at the main wreck site.
As the divers continued to work, they laid aside black and gray rocks, thinking they could be ballast rocks from the ship, and still hoped for large pieces of the shipwreck.
"Then George Robb found a piece of pine that still smelled like pine," Malcom said, explaining that the workers initially thought the charred wood had been used as firewood on board the ship. "But as we continued to explore, it didn't feel like a shipwreck anymore."
The divers had wandered into a section of prehistoric Florida that had once been dry land during the last Ice Age, Malcom said.
When the Ice Age ended, the ocean levels rose sharply for thousands of years, covering much of the land in seawater and burying pine forests under about five feet of sand and sediment and more than 40 feet of water.
Radiocarbon analysis showed the pine cones and burnt wood to be about 8,400 years old, but the burnt characteristic remained a mystery until it was learned that the black and gray rocks also had been burnt and were identified by sanctuary scientist Harold Hudson as fire-altered limestone.
Hudson's theory was confirmed by geologist Eugene Shinn, leading the researchers to believe that a forest fire had, at some point, swept through the prehistoric forest.
While no signs of humanity were revealed in the initial findings, Malcom is not ruling out the possibility of finding some.
In the meantime, he is hoping to continue to work in cooperation with geologists and paleo-ecologists, who are more familiar with the underwater findings.
Representatives from the sanctuary also are interested in learning more about the land mass that once stretched more than 30 miles away from the shores that are now Florida.
"It's pretty incredible that the sea level rose that much, and definitely leads to some interesting questions that we hope people will pursue," said Dave Score, who works for the sanctuary and often deals with submerged cultural resources.
"Obviously, our focus is on shipwrecks, but I also think our mission was to discover, and we've certainly done that," Malcom said, carefully wrapping a pine cone in a saltwater-soaked paper towel until it could be properly conserved.

"Your link to the underwater map sadly does not work anymore. Do you know of a link to a similar site?" That's strange, it still works for me. I don't have another site.

"Have you run across any information that would lead you to believe that a reducing environment may have existed in this area pre-impact? I seem to recall hearing that there was some indication of this from investigations of the cenotes in the Yucatan." Sorry, I don't have anything but claims of a 'city' 2200 feet underwater. I just thought that was to much for subsidence, so....I thought of other possibilities.

"There are acres of erect tree stumps from a forest somewhere off Virginia and I think Hatteras. It's a good lobstering area for dives. "
Yes...At the height of the last ice age the sea level was almost 400 feet lower than today.
On the mid-Atlantic coast, Native Americans almost certainly lived along the shores of Norfolk Canyon (then an estuary) far out on the continental shelf.
I have seen the tree stumps far out in the surf off the Va.-Carolina line... after a storm the sand is swept away exposing the old forest. Marl (a soft gray mud) is exposed with plant stems and roots.

"Carolina Bays...."
This probably includes the largest natural lake in Virginia, Lake Drummond, in Dismal Swamp (about 25 miles from the ocean).
It is quite round and has a clay pan under it. I wonder if iridium traces could be found beneath.

"It is quite round and has a clay pan under it. I wonder if iridium traces could be found beneath." Don't know. They have been arguing about their origins forever. Do a search on 'Carolina Bays' and you can review some of the arguments.
Did you get the link to the map to work?

Yeah, Florida is one giant limestone sponge covered with the black debris of Pleistocene fossils. When canoeing down the Peace River, notice the floor of the river. It's mostly black. The black material is bone fragments, shark teeth, manatee ribs, cat teeth, mastodon teeth, horse teeth, ray barbs, ray teeth (well, they're called that. They're more ridges.) etc..

Underwater Map Of The World With The Water Level Reduced By 310 Feet Hey, um Blam, the website states 110 meters. And last time i checked, 110 meters was 330 feet, give or take a few inches..
I think yer hiding sumthin'...

I wonder if iridium traces could be found beneath.I think this calls for a field trip to obtain core samples!

Dismal Swamp is an odd place, geologically.
It is higher in elevation than surrounding land.
Several streams flow down and out of it. It is like a sponge, with vegetation building up the level each year. Probably due to the pan structure below.

"Hey, um Blam, the website states 110 meters. And last time i checked, 110 meters was 330 feet, give or take a few inches.." Yup...that's what I meant, 330 feet, "that's the ticket, yea, yea."

No mining.
There was the the cutting (over 100 years ago) of 150,000 acres of white cedar timber for house shingles. (now all grown back in bald cypress) It has been deeded to Nature Conservancy.
