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 found prehistoric pine cones along with pieces of yellow pine trees thought to be about 8,400 years old and eventually submerged under the ocean with the end of the last Ice Age.
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.
Just keep in mind that where the article sez, "8,400 years old" it needs to be corrected to "8,405 years old".
Actually, it says, "I spend WAY too much time on FR. 7 years..."
This article is facinating to me.....
After listening to Rush yesterday about cow flatuence...I believe that dinosaur flatuence REALLY left a huge carbon footprint for us....
Doesn't this help to prove that a significant and catastrophic global warming occurred..... back when the earth was flat?
Seriously, good article and compared to many, it was refreshing to read.

Thanks, SC.
That is a daunting task they're taking on with that little sub! It seems like looking for a needle in a haystack. I think there's a fair amount of silt in the GOM too.
Reminiscent of the Aquatic Ape theory, in a way.
