The research team trying to find the original cast in bronze artifact extracted from the site Inupiat Eskimo house is believed to be about 1,000 years.
Artifact looks like a small buckle, researchers at the University of Colorado at Boulder said the notice. As he reached Alaska is still a mystery.
"The goal seems to be older than the house we were excavating at least a few hundred years," research assistant John Hoffecker said in a statement. Hoffecker conducted archaeology excavations at Cape Espe Berg on Alaska Seward Peninsula.
The object has a rectangular bar attached to a circular split ring. It is about 2 inches long and 1 cm wide. It was found in August on one side of the house dug into a beach ridge.
The archaeology excavations are part of a project paid by the National Science Foundation to study the human response to climate change by Cape Espe Berg of AD 800 to AD 1400th archaeologist Owen Mason, a researcher affiliated with the university based in Anchorage, said that six or seven home sites have been excavated.
"The whole plan was to examine how unemployment benefits and social practices changed about 500 years back in time," he told The Associated Press.
The work in the summer of 2011 was the third and final full season for the project. The analysis of animal bones and wooden objects, including parts of boats will follow.
"We try to understand if people hunt whales," Mason said Monday. "It's a very broad topic. Wood is a great story. We need more radiocarbon dates, the dates of several rings of trees. It means the climate history of the wood."
Bronze artifacts were found in three feet of sediment near the entrance of the house by a University of California, Davis, graduate student, Jeremy Hay, he used a screen sieve. Bevel on one side of the bronze and concave on the other hand, indicates the point had been cast into a mold.
Needles of copper found Cape Espen Berg, second home. First Alaska Nat knew the hammer of copper tools, but it is not known melting metal in Alaska, Mason said.
"It would be important if there is metal in Alaska, but I do not see it here," said Mason.
The site is located in the Bering Land Bridge National Preserve House and the origin of the piece was most likely in Korea, China, Manchuria and southern Siberia. The Eskimos of Alaska in the early Northwest Inupiat have been carried across the Bering Strait about 1500 years ago, the researchers said, and passed from generation to generation.
A piece of leather wrapped around the rectangular bar gave a radiocarbon date of about 600.
"It seems premature, based on what we know now about the house, but has not left the house well enough to be sure that our thoughts are correct home before," says Mason.
An archaeologist has proposed a piece of Asia could have been part of the harness horse or ornament. Researchers are looking for East Asian experts to give a piece of bronze.
Mason said that it is likely that the piece of bronze has been washed down to the beach, after a Russian explorer, or Whaler.
"It's totally improbable, in fact, almost impossible, as it is," he said.
The house was excavated a mound hostile was part of a swamp in a sand dune on the coast today.
