The United States has a rich history that researchers are only now beginning to truly understand. Humans likely arrived in North America tens of thousands of years ago, and many of these groups have left behind tell-tale signs of their presence.

Throughout the nation’s varying landscapes, the remnants of varying cultures remain prevalent, shedding valuable insight into the ancient humans who thrived in the US before the arrival of the Europeans. Here are ten of the most fascinating archaeological sites.

America's Stonehenge

One of the most unusual sites in the US is known today as America’s Stonehenge. Comprised of enormous blocks of stones that make up individual passages and chambers, this site is generally considered to have been ceremonial in nature.

Many believe it was used as an enormous astronomical calendar that clearly tracks the solar and lunar events of the years. Researchers have proposed the site was inhabited by a group of astronomers, yet due to the site having no replica elsewhere in the US, some have suggested the original inhabitants came from overseas.

Dozens of these unique carvings dot the landscape, some up to 170 meters in length, which means they cannot be fully appreciated unless you’re above them in the air. To this day, researchers are unsure which group first carved these enigmatic pictures, adding to the mystery and intrigue of these geoglyphs.

The Bandelier National Monument covers a distance of over 50 square miles in New Mexico and shows signs of an ancient human presence dating back over 10,000 years.

The ancient inhabitants were likely drawn to the region due to the abundance of obsidian, which could be used to produce tools. Artifacts recovered in the region showcase a trading network that ventured as far south as Mexico in ancient times. Today, over 23 tribal nations continue to live on the lands of their ancestors in the vicinity of the monument.

Mesa Verde National Park, Colorado

The Mesa Verde National Park officially became a UNESCO World Heritage site in 1978, but the first humans arrived in the region around 9,500 years ago.

Researchers first found the ship’s bell in 1985, over 260 years after its destruction. In 2013, archaeologists also found a small brass plate inscribed with the vessel’s name, which allowed them to say with certainty that this vessel was finally the Whydah Gally. Today, it stands as a reminder of the golden years of piracy in the US.
