The group gathered around a rocky outcrop along the banks of the Aucilla River. They sat around a fire and sharpened their spears. This was an important place. Here, they mined the outcrop for chert, a kind of flint, to make spear points and tools.

Earlier they may have killed a deer and feasted. Later they would break camp and leave behind little, a few spear points, stone tools and a bone or two. Where they came from, where they went and when they first arrived is unknown. Did they live close by or did they visit only when they needed chert?

The desire to answer those questions is what drives the research of Michael K. Faught, assistant professor of anthropology at Florida State University. He knows people last visited the rocky outcrop more than 8,000 years ago. Soil samples indicate that was when the Gulf of Mexico flooded the area. But it was at this particular outcrop, nine miles off the north Florida coast in Apalachee Bay, that a team led by Faught found what may be a 12,000 year-old projectile point, a spear point dating back to the Suwannee era. By all accounts it could be the oldest artifact ever recovered on the continental shelf by professional archaeologists.

Faught, director of the FSU PaleoAucilla Prehistory Project and the university's field school in underwater archaeology, hunts sites out on the Gulf floor which he believes were visited by ancestors of the Clovis people, the hunter/gathers who made the notched point his group found last summer. He thinks those sites would provide answers about when people began to live in Florida. And they may indicate whether people came ashore at the Gulf coast and then moved inland or traveled from the interior to the coast. Faught thinks he's taking the right road to arrive at those answers.

Florida's geography is much different from when hunters of the late Paleo-Indian and Early Archaic periods roamed and lived among the oak hammocks and savannahs along the Aucilla River in the Big Bend region. At that time, North Florida extended about 85 miles farther out into the Gulf.

But starting about 17,000 years ago and continuing for another 10,000 years, a period of global warming melted glaciers and flooded nearly half of what was Florida. Rivers that flow into Apalachee Bay today, like the Ochlockonee, St. Marks and Aucilla, have ancient segments that are now submerged on the continental shelf. Water hides the sites Faught wants to find.

Since 1997, Faught has procured the equipment needed to find the type of terrain where artifacts are likely to be found, trained students to use it and developed the criteria to locate places to investigate. He's confident in his methodology. That's why in the summer of 2000 he invited colleagues to dive into an area that he and his students had identified as a good spot to find artifacts.

In the four summers since the underwater archeology program has operated, a square kilometer of the floor of Apalachee Bay has been mapped with side-scan sonar. So far, 35 sites have been selected for investigation.

Divers have recovered more than 4,000 pieces of chipped stones and several hundred bone fragments from Pleistocene animals including a mastodon, horse and giant sloth. The evidence leads Faught to conclude that there were two periods of occupation along the submerged banks of the Aucilla River. One dates to 12,000 years ago when the sea was 85 miles away. People worked with wood and stone and subsisted on deer and freshwater fish. The second occupation was 8,000 years ago, when the landscape had been transformed to a coastal habitat. At that time people were collecting oysters in the tidal creeks of the river mouth. Faught and the program's graduate students are preparing to submit their findings to peer-reviewed journals early in 2002. Those articles will detail different aspects of the research, offer analysis of the artifacts and the techniques used to find them.

As soon as Cheryl Ward dove to the bottom of Apalachee Bay she thought, “well this is different.” Among the scurrying crabs and brightly colored coral were numerous flakes that she suspected were debris from ancient tool making. Ward is an FSU assistant professor in anthropology.

As she explored the underwater landscape a starfish, missing part of an arm, caught her eye. Next to it was an angled, light colored stone. A piece of flint that someone scraped, filed and fashioned to a point. When she got closer she saw that it was a spearhead. She signaled Faught to come take a look.

“He was so excited,” said Ward. “I could tell that he thought this was important.”

Faught is convinced the point is 12,000 years old because it is an unequivocal example of the type made during a specific era. “We know this kind of point is found in strata underneath other points for which we have radio-carbon dates,” explained Faught. “Once you know the types of points you can make a good estimate of their age.”

Faught wants to go back farther. He wants artifacts that pre-date the Clovis era (about 14,000 years ago). He believes the farther out in the Gulf he goes the farther back in time he'll travel. If Faught is correct his work will further stir a debate about when the first humans arrived in the Americas.

“It just doesn't add up,” he said about the traditional theory that all of the prehistoric settlers of America were people who had crossed a land bridge from Asia into Alaska.

“We don't see the artifacts of early Clovis culture in the far Northwest or Alaska. From my perspective, the best evidence of Paleo-Indian continuity through time anywhere (in the western hemisphere) is in the southeast. And it's with these people, the people who made fluted-point projectiles that we are trying to discover offshore.”

“We don't know when people first came to Florida,” said James Dunbar, an archeologist with the Florida Department of State. “If they might have been maritime, going offshore my help us to figure it out.”

In 1986, an artifact collector passed to Dunbar a letter that Faught wrote seeking information about Paleo-Indian sites in Florida. At the time Faught was a doctoral student at the University of Arizona.

“Talk about underwater archaeology and 99 percent of the public think of shipwrecks and just don't think about the sites that have been drowned,” said Dunbar who works in the Florida Bureau of Archaeology.

Dunbar called Faught and was so intrigued by the discussion he suggested that the two of them go diving in the Gulf of Mexico near the mouth of the Aucilla River.

“I knew after that first dive, that we were onto something,” Faught said.

What struck Faught was that the karst plain that makes up the bedrock of north Florida aids the search for artifacts. That means once a potential site is identified the artifacts are close at hand and not buried under yards of muck built up over thousands of years, as normally occurs in other areas of the continental shelf. Faught found flakes of flint, evidence of tool-making, on the Gulf floor during his first trip.

“Whether they came here from land or from the ocean they are at the Aucilla River drainage system,” said Faught.

The Aucilla originates in Georgia and flows about 25 miles southeast of Tallahassee before emptying into the Gulf near where the Florida peninsula juts out from the mainland. Along its banks are numerous prehistoric sites. The ancient river channel stretches about 85 miles along the Gulf floor. Faught is trying to find the submerged channel and follow it to what was the coast about 13,000 years ago. There he will look for evidence of human habitation.

That he has recovered an artifact that may be 12,000 years old from 15 feet of water, plus numerous other spear points, stone tools and animal bones in Apalachee Bay indicates that Faught knows where to look.

He emphatically maintains that the point was not washed downstream by the river, pushed out to sea by a flood, or placed where it was found by some occurrence other than being dropped on dry land by a human.

“The artifacts are not being moved by the river because they are not beat up and polished. They are pristine sharp and there's a diversity of size and type,” said Faught. “What we are finding is consistent with a rising sea level not with objects being pushed down steam and in and out of sinkholes.”

Clovis hunters were in Florida 13,000 – 14,000 years ago. They are a mystery (see sidebar, page 15). All of sudden evidence of their existence, stone tools and middens for example, appear abruptly in the archaeological record. If they arrived earlier, then it's possible that they hunted the savannas, lived among the oak hammocks and fished the rivers on the continental shelf. If sites dated before the Clovis era are found in the Gulf of Mexico then excavating them may add to the understanding of how people migrated to the Americas. If they are after the Clovis era, excavation will add to the understanding of how people adapted to the rising sea levels when the ice age ended.

The ancient river channel is the key to finding where prehistoric people lived, said Faught. Freshwater attracted animals, the mastodons, giant sloths, horses and camels that ancient people would hunt. Faught assumes because there was dense occupation inland along the riverbanks then he will find evidence of humans down river at the coast. Near the submerged banks, teams of students also have found mastodon teeth, animal bones and stone tools.

Beginning in 1997, Faught's team began searching shallow (10-20 feet) underwater terrain that faintly resembles the land the way it was when hunters armed themselves with spears made from stone. The land, of course, has been highly altered by waves and thousands of storms over the eons. As a consequence, the debris that prehistoric people left behind--tools, charred wood, spear points—has been pushed, tossed and buried by the Gulf waters. Equipped with sonar, Faught identifies the subtle distinctions that indicate the land once was the type where humans most likely tended to gather.

“It helps to know what the past landscape looked like,” said Faught. Sonar imaging, diver observation, excavation and mapping is used to reconstruct the prehistoric terrain. “On land we know the terrain where sites have been found, so we look underwater for what were similar features,” explained Faught.

The information gathered from sonar and divers is made into a three-dimensional picture. After studying the pictures and comparing them to an evolving criteria, spots are selected for further investigation and possible excavation. When anything is found, the area is photographed and analyzed and the data is added to the criteria used to select sites.

“This is significant and pioneering work,” said Dunbar. “Within the profession, most (offshore) work is on shipwrecks. This is broadening the horizon.”
