Most people consider the start of US history to be 1776, but nothing could be further from the truth. There are, in fact, thousands of years of North American history. Who lived there? What did they leave behind? This list explores these questions by taking a look at some of the most interesting and mysterious archaeological discoveries ever made in the United States.
10. Lake Winnipesaukee Mystery Stone
Discovered in 1872 buried close to Lake Winnipesaukee in New Hampshire, the eponymous mystery stone is dark, smooth, egg-shaped, and about 10 centimeters (4 in) tall and 6.4 centimeters (2.5 in) wide. On its surface are a number of carved symbols and images, including a face, ears of corn, and a teepee, among other unknown images.
Questions have emerged regarding the stone: Who made it? And what is it? One theory suggests that the stone may have been made by Native Americans to commemorate a peace treaty between two tribes. Other theories contend that the stone could be Celtic or Inuit in origin.
The mystery was further complicated when researchers investigated two holes in the stone, one at the top and one at the bottom. These holes were drilled with a level of precision that seems inconsistent with the ability of premodern tools. This has led some to believe that the stone may be an elaborate hoax, while it has convinced others that the stone may be a “thunderstone” crafted by supernatural forces.
