In a captivating blend of extreme science and historical sleuthing, veteran journalist Tom Koppel tells the inside story of the quest to discover who first settled in the New World -- and how and when they did it.
For decades the issue seemed moot. The first settlers, we were told, were big-game hunters who arrived from Asia at the end of the Ice Age some 10,000 years ago, crossing a land bridge in the Bering Strait and migrating south through an ice-free passage between two great glaciers blanketing the continent. But after years of sifting through data from diverse and surprising sources, the maverick scientists whose stories Lost World follows have found evidence to overthrow the "big-game hunter" scenario and reach a startling and controversial conclusion: The first people to arrive in North America did not come overland; the came along the coast by water.
Now, for the first time, an award-winning journalist details these provocative discoveries as he accompanies the archaeologists, geologists, biologists, and paleontologists on their intensive search. Writing with crisp and often suspenseful prose, author Tom Koppel takes readers along with the scientists under the sea, into caves, and out to the remote offshore islands of Alaska, British Columbia, and California. Presenting detailed and growing evidence for ancient coastal migration, he shows how new methods of dating, underwater imaging, and biochemical analysis support conclusions based on more traditional scientific inquiry.
Lost World is driven by an eloquent and powerful narrative that brings to life the rich existence of daring maritime pioneers, a sea-faring people who survived in food-laden refuges on the fringes of retreating coastal glaciers. By accompanying the key scientists on their intensive search and recounting with vivid immediacy the risks and failures along with the satisfactions and breakthroughs, Koppel brings to life the quest for that Holy Grail of New World prehistory, the first peopling of the Americas. A fascinating book full of larger-than-life personalities, timeless mysteries, and astonishing discoveries, Lost World is science writing at its best.

Cave of the Bears
"Watch your head," said paleontologist Tim Heaton, ducking as he led the way down into the fissure in the steep rock face, leaving the sunshine and warmth behind. It was cold, damp, and quiet. Underground, away from the droning of the big gasoline generator, there was only the barest murmur of seeping water. But we could see well enough. Thick electrical cables ran into the cave to a few lights that were strung along one side.
We were on Prince of Wales Island, Alaska, in the summer of 1999. The main chamber was tiny and cramped, only about ten feet wide, with a ceiling so low in places that we had to stoop. The rocky floor was wet and uneven, and the farthest nook was only about forty feet back from the entrance. Kneeling on the muddy floor of the chamber and scraping up dirt with a trowel was a slim young guy with a wispy black beard who turned to say hello. Kei Nozaki, from Japan, was one of the student assistants Heaton had brought up from the University of South Dakota for a season of fieldwork. Like us, Nozaki was wearing a caver's helmet and a rain suit over his clothes.
Off to the right, a second and much narrower tunnel sloped away into the shadows. "The cave branches here," said Heaton with the soft western twang of his native Utah. "This is what we call the 'Seal Passage,' because that's where we found so many of the seal bones. And it actually loops around and comes out at another entrance down the hillside a bit. It's got a tight little keyhole shape." I switched on my headlamp and flashlight and stepped down into the passageway to take a look.
Heaton wasn't exaggerating. The dank and constricted little gut had a symmetrical keyhole cross section all the way along the gentle downward grade to where it jogged out of sight maybe fifty feet away. From knee to head height the walls, glistening with moisture, had the shape of a round tube about three feet in diameter. Below that was a sort of lower extension, a slot barely wide enough to put one rubber boot past the other. This telltale keyhole shape resulted, Heaton explained, because initially, when the water table was high, a steady flow of ground water had dissolved the limestone over thousands of years, routing out a subterranean water pipe, a nearly perfect cylinder, what geologists call a "solution tube." At some later time, the water table dropped and water only flowed along the very bottom of the tube. This eroded the rock straight down from the center and carved out the lower part of the keyhole. Much of the limestone on the island, and elsewhere on the southeastern coast of Alaska, was riddled with similar tubes and passages. Some of the caves penetrate entire mountains and have never been fully explored -- a caver's dream.
I figured I would make my way down the length of the seal passage and have a look at the other entrance, but it was so hard to squeeze one foot past the other in the tight slot that I soon had second thoughts. And then I discovered that I couldn't turn around. I was stuck in an awkward crouched position, with cold, slimy stone walls hemming me in on both sides. Being trapped in a mine or buried alive has always been one of my pet phobias. Little fingers of fear crept up my spine, even with Heaton right there, close behind. No, I decided, I did not really need to inspect the other end of that dark, narrow tunnel. I was forced to back my way slowly out and exhaled with relief when I was back in the main chamber.
Heaton chuckled at my discomfort. "I'm used to working under the adverse conditions of caves," he said. "This is my third big excavation on the island." He had done a lot of sport caving as a teenager in Utah -- even meeting his wife Julie at a caving club there -- and still went caving occasionally just for fun. His other hobby was being a ham radio operator. And, at about forty, he was in terrific shape: tall, lanky, and built like a marathon runner.
For Heaton, the difficulty of working in this accessible, relatively level cave was nothing. "There's one cave here on the island where you have to go headfirst down a tight vertical crawlway, which emerges at the top of a 150 foot cliff." Other caves have underground lakes and flowing rivers. There are tight spots where you have to take off your jacket to squeeze through; if you get stuck, nobody can help you. And if the battery-powered headlamp goes out, everything dissolves into stygian blackness. "I do some pretty hefty caving to get at some of the bones. Cave paleontology is a specialty. Even most paleontologists are not used to it. They'd get claustrophobic crawling through these muddy holes," he laughed.
But it's a handy skill to have in his profession. "There's lots of bones in caves." For one thing, animals can find shelter in caves, and those that hibernate, such as bears, use the caves as dens in winter. A big bonus for paleontologists is the excellent preservation of bones, teeth, antlers -- anything made of calcium -- in the alkaline environment of a limestone cave. "Bone doesn't preserve too well outside," said Heaton, pointing to the entrance. "You have the temperature and humidity fluctuations, and the acidity of the forest soil, but as you get inside, the bones become better and better preserved, and more common."
The main chamber where Nozaki was digging was called the "Bear Passage." It was a few bear bones Heaton had discovered years earlier, and the totally unexpected information they provided, that initially made this little cave more interesting to him than the many larger and more physically impressive ones on the island.
But it wasn't bear bones that had brought me here from my home in British Columbia; it was human bones and artifacts.
We went back out into the August sunshine, and Nozaki joined us for a break and to warm up from the chill of the cave's interior. Heaton shut down the generator, and we sat to talk among the fuel drums, buckets, hoses, and other clutter of the work site. We were on a south-facing slope in virgin forest of big hemlock and spruce. Heaton took off his helmet and ran his hand through closely cropped red hair. With the sun in his face, he warmed to the quirky tale of how this remote bear den with the official federal designation 49-PET-408 had become one of the most important ancient archaeological sites in North America.
And he might never have even inspected it if it hadn't been for the weather.
In July 1994 Heaton was back on Prince of Wales Island for the fourth time in as many summers. Its caves were proving to be a fossil gold mine, helping him to unravel the complex story of how and when bears first inhabited the Alaska coast. He was one of two paleontologists, plus geologists, biologists, and enthusiastic amateur cavers, who were exploring and mapping the recently discovered cave system with active sponsorship from the local U.S. Forest Service geologist in charge of the vast Tongass Forest District, Jim Baichtal. Major areas of the huge island, the third largest in the United States, were being logged. In fact, it was the logging that had exposed the entrances to many of the caves. But the Forest Service was willing to postpone the clear-cutting in places where caves were being surveyed, and the Feds provided the Tongass cave project with housing, meals, and transportation.
Heaton's plan that year was to spend only a couple of weeks on the island. His target was a high-elevation site called "Bumper Cave," which ran sixty-five feet back from the entrance in sparse subalpine forest high on the flanks of Calder Mountain, a bald rocky dome that loomed over the island's far north end. I had flown past this stark summit early that very morning in the stolid old Beaver float plane that brought me out from Ketchikan to Port Protection, population fifty. There were no roads connecting the settlement to the rest of the island, and no post office, either. Just a dock, a store, a little lodge, a fish plant, and a scattering of houses, all clinging like limpets to the rocky shore of a tiny sheltered cove.
Jim, a chunky, bearded guy, helped me unload my gear from the plane. Like a few other people who were hanging out on the dock, Jim fished a little for salmon with the small commercial fishing boat that was also his home for the summer. Come winter, he drove a taxi in New York City.
To get from Port Protection to 49-PET-408, I hired a lanky fellow named Bud, who was missing a few teeth and had gray hair that reached halfway down his back. He told me that he had moved up from the Lower Forty-Eight in 1972. He made ends meet mainly by cutting lumber for people with a small, portable sawmill, and collected old stone artifacts off the beaches as a hobby. We had to cruise a few miles around a jutting peninsula in an aluminum skiff with a sputtering outboard. Along the way, Bud took a slight detour to show me his favorite spot for finding ancient adzes and daggers made of a greenish stone, presumably by the Tlingit Indians before they first had contact with the Russians and other Europeans in the 1700s. The tide was low and, sure enough, dozens of sharp flakes of green-gray rock were lying among rounded cobbles near some grounded boom logs that were linked together by massive rusty chains. I was skeptical about some of the pieces of stone that he claimed were artifacts, but Bud just smiled knowingly. "Here," he said. "You're going to the cave. Show these to the archaeologists and see what they say." It turned out that he was right.
Bud dropped me off at a gravel beach that was tucked in behind a tangle of kelp. There was a little cluster of brightly colored tents in a sheltered spot above the beach, and just enough room for me to set up mine. But no one else was around; they were all up at the cave, working. From the beach campsite to the cave was a half hour's trudge through dense forest along a steep, muddy trail that climbed more than 400 feet from sea level. For safety, Heaton and his crew had rigged some of the nearly vertical rock faces with knotted ropes. I was panting and sweating by the time I reached the site. It was a hike that I would make morning and evening for the next five days.
Back in 1994, though, Heaton had no intention of hiking that mile-long trail; in fact, it did not exist yet. He and a colleague had assembled the equipment for their expedition up to Bumper Cave, including camping gear and food for at least ten days. They were even bringing along 1000 feet of fire hose, enabling them to run water from a stream to wash and screen the sediment from the cave for any tiny animal bones they might miss at first glance. Kevin Allred, the Alaska-based leader of the cave project, had discovered and mapped Bumper Cave the previous summer, and had regaled Heaton with the juicy details. It was just littered with bear skeletons, he said, probably seven or eight in all, some of them exquisitely preserved. Millennia-old bones from other caves on the island had already overthrown some long-held assumptions about the Ice Age distribution and migrations of both black bears and grizzlies. Heaton was excited by the prospect that Bumper Cave might round out the new and emerging picture.
But his arrival on the island coincided with the long Fourth of July weekend, which grounded the Forest Service helicopter that was to take him and his gear up the mountainside. Baichtal, the geologist, had arranged for him to stay at a Forest Service camp that was the cave project's home base. With comfortable old wooden bunkhouses and separate buildings for cooking and showers, all overlooking a sheltered arm of the sea, this was not exactly a hardship post. But then the coastal weather closed in, and the helicopter could not fly. Day after rainy and foggy day, Heaton was forced to wait, cooling his heels at the camp, a frustrating thing for a guy who hates to waste a moment.
Waking one morning to see the trees shrouded yet again in mist, he and Allred decided to take a side trip to another cave on the island's extreme northwestern tip that Allred had visited the year before. Allred had heard about it from a Forest Service surveying crew, who first noticed the dark opening in the hillside when they hiked through to plot out future logging roads. The cave's ceiling was so low that the initial designation 49-PET-408 eventually gave way to the moniker "On Your Knees Cave."
Allred and two colleagues had crawled through with their compass, inclinometer, and tape measure back in 1993. Later, they made a scale drawing for the cave project's files, and that might have been the end of it, except that they also noticed some animal bones, in particular the well preserved skeleton of a river otter. When he heard about it from Allred the following summer, Heaton wondered what else the cave might hold.
With the helicopter grounded, Heaton and Allred drove to the end of the main logging road and hiked through the woods out onto a peninsula called "Protection Head." The cave didn't look like much. Inside, it was as Allred had described it. There was the river otter, which was interesting. Gee, imagine an otter coming all this way up from the sea, Heaton said to himself. And there were a few larger bones lying exposed right on the surface. One of them, he thought, was the femur of a grizzly bear. This wasn't a surprise to Heaton. Grizzlies did not inhabit the island in modern times, although black bears did. And though it used to be thought that grizzlies never had, Heaton had been finding the bones of both grizzlies and black bears in many of the caves for years now.
Heaton put the visible bones into plastic bags, labeled them, noted their locations in his notebook, and returned to the Forest Service camp. Eventually the weather cleared, the helicopter took him and his partner up to Bumper Cave, and they collected a wealth of bear bones, which later proved to be from 7,200 to 11,600 years old. It was a highly successful, if short, season. As for On Your Knees Cave, Heaton wrote it off as having much less paleontological interest than many of the other caves on the island. All he had found, after all, were the otter skeleton and a few more bear bones.
His verdict would change drastically a few months later. He had sent off a minute sample of the grizzly bear femur to a specialized laboratory for carbon dating. The lab isolated perhaps a thousandth of a gram of bone protein, called collagen, and sent it on to a nuclear laboratory equipped with a high-energy linear accelerator linked to a mass spectrometer. By what is called accelerator mass spectrometry (or AMS) dating, individual ions of the radioactive carbon isotope, carbon 14, were counted. The results went back to the first lab for analysis.
Back in South Dakota, Heaton eventually received a carbon 14 date of 35,000 years for the bear femur, or three times as old as the oldest bear bone previously found on the island. This placed it well before the peak of the last glaciation. Bones from the other caves already showed that bears had inhabited the island in the final, waning years of the glaciation, around 12,300 years ago. Was it possible that they had survived there right through the most recent advance and retreat of the great ramparts of ice, f...
