The Most Mysterious Places In America

Edward Leedskalnin spent 28 years constructing Coral Castle in Homestead, Florida, but how he did it is something of a mystery. Constructed of massive blocks of limestone averaging 15 tons each that he quarried from nearby, Coral Castle is a haphazard arrangement of standing stones, sculptures, and buildings. There's little explanation for how a 100-pound man from Latvia could have single-handedly quarried, moved, and carved the 1100 tons of stone the structure was eventually comprised of, without heavy machinery. When asked, he simply claimed to know the secrets of the building of the pyramids.

The only eyewitness reports came from a group of kids, who described him working at night and making stones levitate like balloons filled with hydrogen. He claimed to have built the structure in honor of his long-lost love, who abandoned him the day before they were due to marry, leaving him heartbroken. If true, this gives a whole new, and very literal, meaning to the phrase "emotional walls."

The stereotype of Native Americans is one of small groups of nomads, traveling around and living in temporary camps. But while that may have been the case when Europeans arrived in the late 15th century, a few centuries earlier, things were quite different. Evidence for this can be found in Illinois, at a place called Cahokia Mounds. Currently comprised of a group of nearly seventy earthen mounds, it is believed to have numbered over 120 when the site was occupied between 700 to 1400 AD. At its peak, around 1200 AD, the city probably had a population of around 100,000 people, and covered an area of six square miles.

Many skeletons have been found at the site—some buried in obvious ceremony, and others displaying evidence of human sacrifice—but that is not the mystery. Within two centuries of the civilization's peak, the site had been completely abandoned. Since the occupants left behind no writings, little evidence exists to explain why. Even the folklore of local tribes lacks any mention of the city, leading to suggestions that whatever happened must have been so terrible, the events were deliberately forgotten. Or, maybe they just got tired of Illinois.

The Chaco Culture National Historical Park, in northwest New Mexico, is another site that reveals the existence of significant ancient civilizations in North America. However, unlike the people who lived at the Cahokia Mounds site, the occupants of Chaco Canyon built in stone. Distributed over nine miles of the canyon floor, a number of great houses were constructed starting around 900 AD, the largest of which, Pueblo Bonito (pictured), contained up to 800 rooms, and reached up to four stories high in places. Many smaller structures can be found in the surrounding area—some up to sixty miles away—that are connected to the central structures by a sophisticated network of roadways.

The construction of these massive prehistoric edifices often incorporated astronomical arrangements, and demonstrate advanced engineering techniques for the time, but despite the size and complexity of the Anasazi civilization, by the beginning of the 14th century Chaco Canyon was largely abandoned. Mysteriously, while some of the structures show evidence of violence and fire, some were abandoned in such an orderly fashion, entrances were carefully closed up and sealed with clay. This quite possibly suggests the people had every intention to return—except, for reasons unknown, they never did.

Think only crazy people see UFOs? If so, you'll be surprised to learn about the perfectly normal family who moved into Skinwalker Ranch, Oregon and then left after just two years due to paranormal activity. Terry and Gwen Sherman, their kids, and their herd of cattle, moved into Skinwalker Ranch in 1994. They reported seeing a ship the size of multiple football fields, hearing disembodied voices speaking in different languages, and even spotting a seven foot tall man. On 12 separate occasions, they saw floating spheres hovering above the ranch.

Some of their cows disappeared and they found others killed and mutilated. They lost 20 percent of their herd in just 20 months. The Shermans often experienced identical nightmares and took to sleeping together, hoping they would be safer if they were all in one place.

Finally, they'd had enough. They sold the ranch to Robert T. Bigelow, owner of the hotel chain Budget Suites of America, for $200,000 and Bigelow converted the ranch into a research center called the National Institute of Discovery Science (NIDS). The researchers documented additional sightings of UFOs and otherworldly animals until NIDS finally shut down in 2004. If you want to visit Skinwalker Ranch today, you're out of luck, because the current owners have closed it off to visitors. Maybe it's better that way—you don't want to end up like one of the Shermans' cows.

Roanoke Island was home to the first English colony in the New World. It's also the site where nearly a hundred settlers seemingly vanished into thin air. In 1587, John White led a group of settlers to the island, one of a chain of islands off the coast of North Carolina. Less than a year later, White went back to England for supplies, leaving his wife, daughter, and infant granddaughter behind along with the rest of the colony. Although it was meant to be a relatively quick trip (as quick as traveling by ship between England and America could be in those days), war delayed his return for nearly three years. When he returned, he found the colony abandoned and looted, with no trace left of the settlers or his family.

No one knows what happened to the settlers. The only two clues were the word "Croatoan" carved into a post and the letters "CRO" on the trunk of a tree. This led some to believe they may have traveled to Croatan Island, or been killed by Native Americans or absorbed into their tribes. Or perhaps they tried to sail back to England, only to be lost at sea.  

In 1998, two teams of archeologists excavated the areas near Roanoke Island, using a map that White had drawn. They found possible evidence of the settlers, including pottery, a ring, and part of the hilt of an iron rapier. They theorized their findings meant the settlers did indeed join the Native American tribes near Roanoke. But why was the island looted? And why, if they hadn't been killed, didn't White's family try to find him? Those questions still remain unanswered.

If you fly a helicopter over the Bighorn Range in Wyoming during the summer, you'll see something incredible: a gigantic medicine wheel. It's 80 feet across and 28 spokes emanate from its center. There is a large cairn, or circle of rocks, in the middle, and six on the outside of the main circle.

The mysterious thing about the medicine wheel is its accuracy. After researching the wheel, archaeo-astronomer Jack Eddy suggested that it was built to predict the position of the stars and the sun during the summer solstice. He found that the way the outer cairns connected pointed to different celestial events. By sitting in one cairn and looking at another, you can see where the sun rises and sets during the summer solstice. Others pinpoint the spots in the sky where stars reappear at dawn after they've been covered by the sun's light for a season.

Many different Native American groups use the medicine wheel to do the Sun Dance ritual, seek visions, and make prayer offerings. It's also a registered National Historical Monument. You can hike up to it in the summertime, so don't worry about renting a helicopter (unless you really want to).

In July of 1947, a rancher named Mac Brazel in Roswell, New Mexico discovered strange debris in his sheep pasture. He called the sheriff, who called the local army air field, who sent intelligence officer Major Jesse Marcel out to the site to investigate. Marcel looked at the debris and concluded that it was the remains of a fallen flying saucer. The next day, the Roswell Daily Record put out an article headlined "RAAF Captures Flying Saucer on Ranch in Roswell Region."

That same day, officials investigated further and declared that the debris was actually a destroyed weather balloon. The next day the Daily Record printed a retraction of their original story, and an embarrassed Major Marcel shared that he had been wrong. Later on, it came out that the weather balloon story had, in fact, been a cover up. The debris in Brazel's yard actually came from Project Mogul, a highly classified military project, in which scientists had been sending out high altitude balloons containing sound sensors with the goal of spying on nuclear tests in distant locations.

Despite the emergence of this new information (or perhaps because of it), many still believe that Roswell is the site of a massive government cover up. What do you think?

Freelan Oscar Stanley arrived in Estes Park, Colorado in 1903, sick with consumption. Within one season, he fully recovered, and vowed to stay and make a grand hotel in this little town in the wilderness. In 1906, he built The Stanley, an East Coast style hotel, the likes of which had never been seen in the area before. Some guests claim that Stanley loved the hotel so much he can still be seen roaming the lobby and that his wife, Flora, still presses down keys on the piano, which she played to entertain guests in the heyday of the hotel.

The grand hotel gave new life to the town, and by 1917 it was an official municipality. But then, the hotel fell into disrepair. In the 1970s, it was in danger of being closed down — only to be rescued by an unlikely savior. Stephen King stayed at the hotel for one night, and was inspired to write The Shining, one of his most popular novels. King stayed in room 217, and in the novel, a clairvoyant character is told not to enter that room. 

Since then, the hotel has become known as a center for ghosts and spirits. If you visit the Stanley, make sure to take their Night Spirit tour to learn how to interact with ghosts. But, the website warns, "Due to the fact that spirits are not on payroll, we do not guarantee any interactions."
