To find traces of the ancient indigenous people at the bottom of Lake Ontario
Pioneers the use of drilling Geology-style novel to detect the presence of past civilizations
He used a team of Canadian scientists core drilling Geology along the lines from the bottom of Lake Ontario to collect evidence from the manufacture of machinery and duckhunting perhaps even by the indigenous population of old about 10,000 years ago, the first discovery of its kind in North America, one can point a way to achieve more achievements in underwater archeology in all parts of the world.
Led by researcher Lisa Sonnenburg of McMaster University in Hamilton, Ont., The team took sediment samples from a shallow section of Rice Lake-a popular summer vacation spot northeast of Toronto-where prehistoric First Nations were known to have camped soon after the glaciers retreated at the end of the last ice age. Took a team led by researcher Lisa Sonnenburg from McMaster University in Hamilton, Ontario, and samples of sediment from the lagoon Section Rice and vacation spot summer popular north-east of Toronto, where he was known before the date to the First Nations and hangs shortly after the retreat of glaciers at the end of era the last glacial.
The scientists found more than 150 tiny flakes of quartz in the lake's murky depths-strong evidence that an ancient shoreline, submerged long ago, was used by some of Canada's earliest inhabitants as a site for manufacturing spear points, scrapers and other tools for fishing and hunting. The scientists found more than 150 small chips of quartz in the evidence mysterious depths of the lake that the strength of the old coastline, soaked for a long time, was used by some residents of Canada as soon as the location for the manufacture of spear points, scrapers and other tools for fishing and hunting.
The discovery not only sheds new light on the activities of those prehistoric people, but also pioneers a novel method of detecting the presence of ancient aboriginals in what are now drowned landscapes-a technique with huge research potential in Canada's Great Lakes region and many other places around the world where suspected settlement sites have became inundated over time. Discovery not only sheds new light on the activities of these prehistoric people, but also pioneers new way to detect the presence of indigenous peoples old in sink now landscape, technology with the research capacity across the region of Canada the Great Lakes and many other places all over the world where became flooded sites suspected of a settlement with the passage of time.
The team's analysis of telltale markings of human activity on the quartz fragments-known as "microdebitage" among archeologists-shows that the technique "offers a reliable quantitative method for narrowing search areas and for identifying new areas of underwater archeological potential," the researchers conclude in a study published in the July issue of the journal Geology. Group analysis of telltale signs of human activity on quartz fragments, known as "microdebitage" between shows, the archaeologists that this technique "method provides a reliable quantity to narrow the areas of research and identifying new areas of potential archaeological under water," the researchers conclude in a study published in the July Journal of Geology.
Sonnenburg said the team targeted "what we thought was an old shoreline" and that the drill cores proved that's "exactly what it was." Sonnenburg said team had targeted "what we thought was the old coastal line," and that it proved to the core drilling of the "exactly what it was."
She recalled "staring down the barrel of a microscope" for a long time before beginning to see quartz chips at a consistent layer of sediment, about two metres deep, that suggested the ancient occupation of the site. She referred to "staring down the microscope barrel" for a long time before we see the beginning of quartz chips in a fixed layer of sediment, and about two meters deep, and suggested that the occupation of the old site.
"I hyperventilated a little bit," she said of the discovery. "I hyperventilated a bit," she said of the discovery.
While looking for larger artifacts in a submerged landscape amounts to searching "for a needle in a haystack," Sonnenburg said using the coring technique to find evidence of toolmaking could be useful at many potential archeological sites-especially in the Great Lakes area, where shifting shorelines have flooded many potential archeological sites since humans first began occupying the continent more than 10,000 years ago. While looking for more works of art in the quantities of landscapes submarine to search "for a needle in a haystack," said Sonnenburg using drilling technology to find evidence of making machines that can be useful in many archaeological sites of potential, especially in the Great Lakes region, where turned and fled from the beaches many archaeological sites of potential human beings since the occupation began on the continent of more than 10000 years ago.
The discovery of now-submerged archeological sites is expected to provide breakthroughs in the coming years for researchers trying to trace the initial peopling of the Americas via Pacific coastal routes in present-day Alaska, British Columbia, Washington, Oregon and California. It is expected that the discovery of archeological sites now submerged, to provide breakthroughs in the coming years to researchers in an attempt to trace the initial silence of the Americas across the Pacific coastal roads in Alaska at the present time, British Columbia, Washington and Oregon and California.
