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.

“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. “

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

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.

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.

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.”

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

Every time other people arrived at the Americas, Siberia crossed Beringia, an area of ​​land and sea between Russia and Canada and Alaska. It is now covered with water, however, once a land bridge that connects them.

The in Alaska with the oldest evidence of human housing is Swan Point, in the region of the central-east of the State. In addition to the 14,000 -year -old teams and homes, gigantic bones were discovered there.

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.

For decades after Whiteman’s discovery, the idea of ​​the mavens that the other people of Clovis were the first to cross the Bering d’Aring land bridge about 13,000 years ago. It is believed that the estimates of the arrival of humans are now at least 15,000 years ago.

Archaeologists discovered the bones of the child in 2013. Local teams call it xach’ite’anenh t’eede gay, or dawn girl. Genetic tests revealed that the 11,300 -year -old baby belonged to a Amerindian population in the unknown past, the ancient Beringios.

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.

Located in the Navajo nation, Celly Canyon has magnificent perspectives of the desert and thousands of years of human history. Centuries ago, the ancestral teams and Hopi have planted cultures, created pictograms and built cliff houses.

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.

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. Important buildings were sitting on the most sensible giant mounds, which the Mississippiens built by hand, The Guardian reported.

The population built posts of posts, which an archaeologist called “Woodhenges”, as a type of calendar. In the solstices, the sun rises or lies aligned with other mounds.

After a few hundred years, the population of Cahakia decreased and disappeared by 1350. Its largest mound remains, and the safe facets were rebuilt.

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

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

The population was also practical, discovering irrigation systems and structure techniques, such as thick walls and shaded spots, to help them in the warm and dry climate.
