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 aides tell how the first humans came here to North America. It’s a mystery precisely how and when other people arrived, although it’s widely believed that they crossed the Bering Strait at least 15,000 years ago.
“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. “
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 giant sloths roam what is now New Mexico, when it is greener and wetter.
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 those fossilized fingerprints between 21,000 and 23,000 years old. If the dates are correct, previous impressions to other archaeological sites in the United States, raising interesting questions about what those other people were and how they came to the southwestern state.
“Where do they come from?” Feder said. “They do not harden in New Mexico. They will have to have come from another place, which means that there are still older places. ” Archaeologists have simply not discovered them yet.
While they can absorb the white and homonymous sands, PAS footprints are banned 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 have discovered evidence of human homes that seemed to have between 12,000 and 13,000 years, belonging to the Clovis culture. For a long time they would have been the first to cross the Bering land bridge. Humans who have arrived in North America before this organization are called before Clovis.
Feder said that Advasio had meticulously looked for the site, but that 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.
The excavation itself is exhibited in the History Center of Heinz, which allows you to see a search in person.
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.
Some scientists say humans would have possibly traveled along the West Coast at that time, when glacial capitals covered Alaska and Canada. “People who employ boats, who employ canoes can also jump up this coast and gather in North America long before those glacial bodies cut off,” Feder said.
Cooper’s ferry is in the classic nose of the Perce nose, which the land administration office has in public property.
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.
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.
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.
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.
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.
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.
According to this research, humans would possibly succeed in Alaska about 20,000 years ago.
Pictograms can have a non -secular and practical meaning, but also to capture an era in which the teams gathered and mix, 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.
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.
The other people of Navajo, also known as Diné, still live in Canyon de Chelly. Diné Alastair journalist Lee Bitsóí recently wrote about some of the sacred and taboo areas. They come with Tsé Yaa Kin, where archaeologists have discovered human remains.
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.
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.
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.
