The United States is under 250 years old, but some of its maximum archaeological sites are older than Vikings sailors, the Roman empire and the pyramids.

“As we return to time, while we have other people who are getting smaller and smaller, locating those positions and interpreting them becomes increasingly difficult,” said archaeologist Kenneth Feder a Business Insider. He is “ancient America: fifty archaeological sites to see through yourself. “

Many of those puts are open to the public, so you can see the old story of yourself.

For decades, scientists had been finding evidence of human habitation that all seemed to be around 12,000 to 13,000 years old, belonging to the Clovis culture. They were long believed to have been the first to cross the Bering land bridge. Humans who arrived in North America before this group are often referred to as pre-Clovis.

At the time, skeptics said that the radiocarbon dating evidence was flawed, AP News reported in 2016. In the years since, more sites that appear older than 13,000 years have been found across the US.

Feder said Adovasio meticulously excavated the site, but there’s still no clear consensus about the age of the oldest artifacts. Still, he said, “that site is absolutely a major, important, significant site.” It helped archaeologists realize humans started arriving on the continent before the Clovis people.

The dig itself is on display at the Heinz History Center, allowing visitors to see an excavation in person.

One site that’s added intriguing evidence to the pre-Clovis theory is located in western Idaho. Humans living there left stone tools and charred bones in a hearth between 14,000 and 16,000 years ago, according to radiocarbon dating. Other researchers put the dates closer to 11,500 years ago.

These stemmed tools are different from the Clovis fluted projectiles, researchers wrote in a 2019 Science Advances paper.

Some scientists think humans may have been traveling along the West Coast at this time, when huge ice sheets covered Alaska and Canada. “People using boats, using canoes could hop along that coast and end up in North America long before those glacial ice bodies decoupled,” Feder said.

Cooper’s Ferry is located on traditional Nez Perce land, which the Bureau of Land Management holds in public ownership.

In the early 1980s, former Navy SEAL Buddy Page alerted paleontologists and archaeologists to a sinkhole nicknamed “Booger Hole” in the Aucilla River. There, the researchers found mammoth and mastodon bones and stone tools.

They also discovered a mastodon tusk with what appeared to be cut marks believed to be made by a tool. Other scientists have returned to the site more recently, bringing up more bones and tools. They used radiocarbon dating, which established the site as pre-Clovis.

“The stone tools and faunal remains at the site show that at 14,550 years ago, people knew how to find game, fresh water and material for making tools,” Michael Waters, one of the researchers, said in a statement in 2016. “These people were well-adapted to this environment.”

Located in the center of Oregon-South, the caves seem to be a piece of the puzzle that indicates how humans have the continent thousands of years ago.

The Federal Land Management Office owns the land where the caves are located, and are signed at the beginning of historical places.

Researchers think this domain was a type of seasonal hunting camp. While the mammoths returned safe periods for years, humans would adhere to them and killed them, offering abundant food to hunters-gatherers.

In 1929, James Ridgley, 1929, 1929, discovered gigantic bones with striated projectile problems near Clovis, in New Mexico. The other Clovis people who made these teams were named for this site.

One of the reasons why the dates of the human profession in North America are so debatable is that very few old remains have been found. Among the oldest, there is a Sun river boy up, or Xaasaa Na ‘, in the middle of Alaska.

The artifacts that the equipment left implies that the site has been used and for many years and was an assembly point for trade. People have brought equipment and rocks at 800 miles away. The remains of deer, fish, frogs, caimanes, nuts, grapes and other foods have given archaeologists a review of their nutrition and daily life.

The 4 galleries involve photographs of life size of anthropomorphic and animals figures in what is known as the Canyon barrier style. Much of this art is in Utah, produced through the archaic culture of the desert.

Pictograms can have a non -secular and practical meaning, but also capture a time when the teams gathered and mixed, according to the Utah Natural History Museum.

In the 1860s, the United States government forced 8,000 Navajo to move to Fort Sumner in New Mexico. Fatal adventure is known as the “long walk. ” Finally, they were able to return, their houses and their cultures were destroyed.

A white walk is the one that is open to the public without a Navajo or NPS Ranger guide.

The Mesa Verde National Park has a large number of homes, adding the Palais de Falaises. It has more than one hundred rooms and approximately two dozen kivas or ceremonial areas.

With the help of dendrocronology or trees dating, archaeologists learned when the ancestral people built some of those structures and that emigrated outside the doors of the region through the years 1300.

Feder said it was his favorite archaeological site he visited. “You don’t need to leave because you can’t be real,” he said.

Tourists can see many of those housing on the road, but some are also available after a walk. Some want more tickets and can congested, Feder said.

At that time, he is booming with hunters, farmers and artisans. “It’s an agricultural civilization,” Feder said. “It is a position where raw fabrics arrive thousands kilometers away. ” The researchers also discovered articular wells, potentially discovered in human sacrifices.

Although Cahokia is open to the public, the portions are recently closed for renovations.

Feder said that the accommodation is quite accessible, with a short walk along a path to see it, visitors cannot enter the construction itself.
