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.

Many assistance say how the first humans arrived here in North America. It is a mystery precisely how and when other people arrived, although it is widely believed that they crossed the Bering Strait at least 15,000 years.

Some sites, such as White Sands and Cooper’s Ferry, have skeptics about the precision of their age. However, they give a contribution to our understanding of some of the first Americans.

Others are more recent and the other cultures stand out than throughout the country, with complex buildings and eliminating pictograms.

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

Prehistoric camels, mammoths and other giant people have traveled, which is now new, when it is greener and more humid.

While the weather warmed about 11,000 years ago, Lake Otero Water fell, revealing the digital footprints of humans who lived among those extinct animals. Some even to stick to a vague, providing a rare review of the habit of the old hunters.

Recent studies place some of these fossilized digital footprints between 21,000 and 23,000 years. If the dates are correct, the prior impressions to other archaeological sites in the United States, raising interesting questions that those other people were and how they reached the state of the southwest.

“Where do they come from?” Feder said. “Not parachute to the new Mexico. They will have to come from another place, which means that there are still older places. ” Archaeologists have simply not discovered them yet.

While they can absorb white and homonymous sands, Pas’s footprints are prohibited lately.

In the 1970s, archaeologist James, Mr. Adovasio, caused controversy when he and his colleagues that the stone team and other artifacts discovered in southwest Pennsylvania belonged to humans who had lived in the region 16,000 years ago.

Feder said that Advasio meticulously registered the site, but there is still no transparent consensus on the age of the oldest artifacts. However, he said: “This site is surely a vital, vital and vital site. ” This helped archaeologists realize that humans began arriving in the continent against the people of Clovis.

A site that has added intriguing evidence to the prior to the cloud is in the west of Idaho. Humans living there have stone equipment and carbonized bones in a house between 14,000 and 16,000 years, according to the radiocarbon dating. Other researchers approached the dates 11,500 years ago.

These rod teams are other Clovis harassed projectiles, researchers wrote in a 2019 clinical magazine.

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.”

Since the site is both underwater and on private property, it’s not open to visitors.

Scientists study coprolites, or fossilized poop, to learn about the diets of long-dead animals. Mineralized waste can also reveal much more. In 2020, archaeologist Dennis Jenkins published a paper on coprolites from an Oregon cave that were over 14,000 years old.

Radiocarbon dating gave the trace fossils’ age, and genetic tests suggested they belonged to humans. Further analysis of coprolites added additional evidence that a group had been on the West Coast 1,000 years before the Clovis people arrived.

Located in southcentral Oregon, the caves appear to be a piece of the puzzle indicating how humans spread throughout the continent thousands of years ago.

The federal Bureau of Land Management owns the land where the caves are found, and they are listed on the National Register of Historic Places.

Whenever people arrived in the Americas, they crossed from Siberia into Beringia, an area of land and sea between Russia and Canada and Alaska. Now it’s covered in water, but there was once a land bridge connecting them.

The site in Alaska with the oldest evidence of human habitation is Swan Point, in the state’s eastern-central region. In addition to tools and hearths dating back 14,000 years, mammoth bones have been found there.

Researchers think this area was a kind of seasonal hunting camp. As mammoths returned during certain times of the years, humans would track them and kill them, providing plentiful food for the hunter-gatherers.

Although Alaska can have a richness of archaeological evidence of the first Americans, it is also a difficult position to dig. “His excavation season is very close and expensive,” Feder said. Some require a helicopter to achieve, for example.

The researchers who examine the site began to realize that the artifacts discovered on the site belonged to other cultures. Clovis’s problems are larger than Folsom flutes, which were first discovered in another archaeological site of New Mexico.

Blackwater Draw Museum of the University of New Mexico in the East of New Mexico provides the archaeological site between April and October.

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.

Based on the child’s genetic information, the researchers learned that he was connected to fashion asleans, but not directly. His non -unusual ancestors began to remarry genetically 25,000 years before dividing into two teams after a few thousand years: the ancient Berignians and the ancestors of the fashionable Americans.

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.

You can see the world heritage site through yourself throughout the year.

Although it rises, the multicolored walls of the Horseshoe canyon have attracted visitors for a long time. Some of its artifacts return between 9,000 and 7,000 a. C. , but its pictograms are more recent. Some tests date from safe sections of around 2,000 to 900 years.

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.

It is a complicated walk to succeed in pictograms (and the NPS warns that it can be dangerously hot in summer) but it is seeing in person, Feder said. “These are artistic geniuses,” he said about artists.

More than 900 years ago, the other town of Puebloan built the White House, which bears the name of the shadow of their clay. Its upper floors are sitting in a sandstone cliff, with a transparent fall of the windows.

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.

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.

Cahokia called one of the first cities in North America. Not far from St. Louis existing, around 10,000 to 20,000 people lived in dense colonies about 1,000 years ago. The important buildings were sitting on the most sensible giant mounds, which the Mississippiens built by hand, The Guardian reported.

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.

Presented in a limestone cliff in Camp Verde, Arizona, this is an apartment, not a castle, and is not connected to Sovereign Aztec Montezuma.

“These other people were architects,” he said. “They had a feeling of beauty. “
