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.

“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.

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.

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

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.

They also discovered a mastodon defense with what seemed to reduce the marks through a tool. Other scientists have returned to the site more recently, raising more bones and tools. They used a radiocarbon dating, which established the site as a pre-clavis.

“The stone machinery and on the site show that at 14,550 years, other people knew how to locate the game, the new water and the device to make machinery,” said Michael Waters, one of the researchers, in a press release in 2016 “. ” These other people were well suitable for this environment. “

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

Scientists examine coprolitos or fossilized peanut, to be informed more about long and fast animals diets. Mineralized tea can also reveal much more. In 2020, archaeologist Dennis Jenkins published an article on the coprolitos of an Oregon cave that is over 14,000 years old.

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

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.

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.

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.

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 the Congo Canyon. 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.

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.

With the help of dendrocronology or trees dating, archaeologists learned when the ancestral people built some of those structures and that emigrated outside the doors of the region through the years 1300.

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. The 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.

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