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.

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.

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.

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.

The excavation itself is exhibited in the History Center of Heinz, which allows you to see a search in person.

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.

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

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.

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.

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.

Extending more than 80 feet long and five feet high, rows of curved poverty are wonderful when it shows from above. More than 3,000 years ago, the hunters-gatherers built them in tons of land. Scientists do not know precisely why other people have built them, whether ceremonial or a state demonstration.

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.

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 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.

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.

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

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.

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. “
