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 tell the story of how the first humans arrived here in North America. It is still a mystery precisely how and when other people arrived, it is widely believed that they crossed the Bering Strait at least 15,000 years ago.

Others are more recent and highlight the other cultures than throughout the country, with complex buildings and illuminating pictograms.

Prehistoric camels, mammoths and giant lazy people wandered for what New Mexico is today, when it was 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 footprints between 21,000 and 23,000 years old. If the dates are precise, the footprints are prior to other archaeological sites in the United States, which raises intriguing questions about who those other people were and how they reached the state of the southwest.

“Where do they come from?” Feder said. No parachute to New Mexico. They’ll have to come from somewhere else, which means there are still older sites. “Archaeologists simply haven’t discovered them yet.

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

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.

At that time, the skeptics said that evidence of appointments in the imperfect radiocarbon, AP News reported in 2016. During the years that followed, more places that seem greater than 13,000 years in the United States have been discovered.

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

Some scientists that humans had possibly traveled along the west coast at that time, when glacial capital letters covered Alaska and Canada. “People who use boats, who use canoes can also jump through this coast and meet in North America long before these glacial bodies are cut,” Feder said.

Cooper’s ferry is in the classic nose of the Perce nose, which the land administration office has in public property.

In the early 1980s, Navy Seal’s old page of the page alerted the paleantologists and archaeologists of an abyss nicknamed “Booger Hole” on the Aucilla River. There, Mom and mastodonic bones and stone tools.

Since it is underwater and personal property, it is not open to visitors.

Radiocarbon dating has given fossil lines, and genetic tests reported that they belonged to man. A deeper investigation of the Coprolitos added more evidence that an organization on the west coast 1,000 years before the arrival of the people of Clovis.

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.

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.

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.

According to this research, humans would possibly succeed in Alaska about 20,000 years ago.

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.

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.

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.

In early 1900, two shaped the Leling Association of Coliff Coliff, hoping to maintain the ruins in the state region of the Southwest. A few years later, President Theodore Roosevelt signed an invoice that designates the Green Mesa as the first national park aimed at “maintaining the works of man. “

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.

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.

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.

The other people of Sinagua have designed the construction of five stories and 20 rooms around 1100. It is curved to adhere to the herbal line of the cliff, which would have been more complicated than simply making a correct construction, Feder said.

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.

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