These Are the Most Incredible Archeological Sites in America

Bandelier National Monument

Starting our list of the most incredible archeological sites in America is the Bandelier National Monument in New Mexico. Something you may notice from now on and moving forward is that there are plenty of monuments and archeological sites in this stunning western state.

The Bandelier National Monument preserves the homes and territory of the Ancestral Puebloans. The artifacts and structures standing date back to around 1150 and 1600 AD. This incredible monument’s surface area is 33,677 acres, so there is plenty to explore. While here, you can see the impressive Tyuonyi construction, multi-story dwelling, and more. If you’d like to learn more about this archaeological site while visiting, you can also enter the visitor center, which has exhibits, artifacts, and life-size dioramas.

Hopewell Ceremonial Earthworks

Another incredible archeological site in the United States is the Hopewell Ceremonial Earthworks in Ohio. You can find some of these earthworks and burial mounds in the Hopewell Culture National Historical Park. This wonderful UNESCO World Heritage site features eight ancient Indigenous ceremonial earthworks built 1,600 to 2,000 years ago. At these earthworks, artifacts have been found that indicate the people interacted with others from the Yellowstone basin and Florida. Many of the mound artifacts found are now in the British Museum. Ephraim George Squier and Edwin Hamilton Davis were the first to excavate the site.

Newspaper Rock

Newspaper Rock is more than just a rock. It’s a well-preserved part of history dating back about around 2,000 years ago. This large rock panel includes carvings from the Archaic, Anasazi, Navajo, Anglo, Fremont, Pueblo, and Anasazi cultures. You can find this old rock panel in Utah at the Newspaper Rock State Historic Monument.

On the rock are over 650 carvings. It is one of the largest collections of petroglyphs in the world.

Chaco Culture National Historical Park

Although in no particular order, the third on our list is the Chaco Culture National Historical Park, which is also in New Mexico. This unique place holds a lot of meaning. It’s a sacred spot. The Chaco Culture National Historical Park is massive, with a surface area of 33,977. Despite its impressive size, though, this historical park gets few visitors, often less than 50,000 a year.

Incredible structures remain throughout the Chaco Culture National Historical Park. Here, you can see Chacoan complexes like Pueblo Bonito, which was built between AD 850 and AD 1150. Also in the park is the Pueblo Alto, an Ancestral Puebloan great house with 89 rooms.

Mesa Verde National Park

One of the most well-known and visited archaeological sites in the United States is in Mesa Verde National Park. This national park was established on June 29, 1906, and has a surface area of 52,485 acres. Over half a million people visit this national park every year to see the Ancestral Puebloan archaeological site. 

The cliff dwellings, in particular, grab many people’s attention. These dwellings are very well-preserved and were built hundreds of years ago as many Ancestral Pueblo people moved. Some of the structures are the Cliff Palace, Spruce Tree House, Long House, and Balcony House. Also in the national park is a Sun Temple.

Legend Rock Petroglyph Site

Not all archaeological sites in the United States are in the South West. Another incredible one is the Legend Rock Petroglyph Site in Wyoming. This unique site is located near Hot Springs State Park. On the face of the rock are over 300 individual petroglyphs. The origin and date of these carvings, though, are still being debated.

The Legend Rock Petroglyph Site is massive. It’s not just a large boulder on the side of the road. Instead, the 300 petroglyphs are spread out on a 1,312-foot-long vertical cliff. This site has been on the National Register of Historic Places since 1973.

Aztec Ruins National Monument

Next on our list of the most incredible archeological sites in America is the Aztec Ruins National Monument in New Mexico. Within this national monument are some of the best-preserved Chacoan structures in the world. The Pueblo Indians constructed them.

The Aztec Ruins National Monument was created on January 24, 1923. It’s small, with a surface area of 318 acres, but is impressive to view. The structures were likely constructed around the 12th and 13th centuries.

Seminole Canyon State Park & Historic Site

Moving to Texas, you can find the Seminole Canyon State Park & Historic Site. Throughout the park, you can find old cave art and artifacts thousands of years old. The cave art is estimated to be from around 7,000 B.C. You can see this impressive cave art in the Panther Cave and Fate Bell Shelter.

This park, though, features a lot more than just archeological discoveries and history. While here, you can also camp, view wildlife, and bird watching. Some of the best overlooks in the park are the Presa Canyon Overlook and the Panther Cave Overlook. Another must-visit point of interest in the Seminole Canyon State Park & Historic Site is the Maker of Peace, a stunning statue honoring the people who drew the pictographs on the walls.

Palo Duro Canyon State Park

Palo Duro Canyon State Park offers jaw-dropping views and thousands of years of history underneath your feet and all around you. Unlike the others on this list, though, you won’t be walking up to massive structures left behind after hundreds or thousands of years. Still, several archaeological sites are protected by the law in the park. Sampling and excavating can tell us more about the people who lived on the land of Palo Duro Canyon State Park thousands of years ago. This Texas state park is also excellent to visit if you want to glamp, hike, or horseback ride.

Cahokia Mounds State Historic Site

Last but not least is the Cahokia Mounds State Historic Site in Illinois. This impressive spot is a UNESCO World Heritage Site and National Historic Landmark. The Cahokia Mounds State Historic Site is the site and what remains of a pre-Columbian Native American city. It was an active city from about 1050 to 1350 CE. Although the ancient city was larger, the park’s surface area is 2,200 acres and contains about 80 mounds. At the city’s peak, it may have contained over 100 earthworks.
