At the bottom of Lake Michigan is a Stonehenge-like structure. The rocks form a rough-looking circle, the limestone blocks are believed to weigh in the tons. One of the rocks allegedly has a drawing of a mastodon on it.
When it was first discovered in the late 19th century by workers dredging the lake for sand and gravel. Initially, they thought that this was a natural formation. However, after further research, it was revealed that the structure was man-made.
As to the question of who created the structure, workers and academics had multiple theories, ZME Science reports. The one that made the most sense to them was that what they found used to be a Native American site, likely where they would hunt.
More answers were forthcoming as technology advanced. Using remote sensing techniques, more information was able to be gathered about the structure.
Despite the belief that the limestone blocks were super tall, they were only about three and a half feet high. And they were about five feet wide.
The belief that the structure was prehistoric is true. Archeologists have determined that it was formed between 1000 and 1500 CE. Which brings the drawing of the mastodon into focus. According to Historic Cornwall, they believed it was possible that the humans were hunting the fierce mastodon.
Lake Michigan's Stonehenge structure is currently listed as a National Monument and is one of the most popular lake-based attractions in the world.
Bottom Of Lake
Researchers have begun piecing together the mystery of the Lake Michigan Stonehenge structure. They have taken the information available to them and started to form theories about how it was brought together, when it happened, and how it ended up at the bottom of the lake.
Some geologists who have worked on the figuring out the mystery have placed the formation of the structure in the late Woodland Period. They point to the fact that it seems to be made of friable sandstone. GeoScience World informas us that it is a material that loses its cement binding over time.
They believe that melting ice covered the land where the structure stands. Over time, the mass sank lower and lower into the water until it was hundreds of feet below the surface of the lake.
Some people argue that the melting ice could have formed the structure. This group say that it's known water has the power to move items around, and that the imperfect nature of the circle would suggest that something larger was at play.
However, that argument is offset by the carvings on the rocks. According to Michigan State University, the mastodon, for instance, points toward human involvement in the formation. They also tend to forget one of the bigger revelations from the last exploration of the structure.
While at first, the structure seems to be in the form of a crude circle, some archeologists have pointed out that it seems to be more in the shape of a "V" that is rounded off.
One of the people who has researched the structure and is in the know about a lot of the information is researcher Dr. Mark Holley.
Dr. Holley has been looking into the Lake Michigan Stonehenge mystery since 2007. He believes that things are not what they seem with it. For instance, he argues that some of the headlines are more sensational than what they need to be. The structure, he believes, is intriguing but not all what it is made out to be.
One of the things he points to is that the alleged picture of the mastodon could be nothing more than a series of etches that aren't supposed to resemble anything.
He wrote in a report: "They want to actually see it. Experts in petroglyphs generally don't dive, so we're running into a little bit of a stumbling block there."
In the same report, Dr. Holley goes on to blame politics for the research being stalled. WRKR reports that he claims that there have been some officials who limited the amount of money that was allocated to the research project.
Will the truth about the structure ever been known? It appears that there is forward movement in finding out how it formed and what went into it, ending up at the bottom of the lake. But there is still a lot of work to do to resolve this mystery.
