Underwater archaeologists led by Dr. Mark Holly Analysis The image of the Swedish people on the bottom of Michigan lake, regained in 2007, and also checked more locations in May 2025. New technologies have increased the details of images, which can detect mysterious megalith called “underwater stonehenge” – like the famous monument in the UK.
The photos recorded two stone circles with a diameter of about six years or two meters, located more than one kilometer apart and connected by a winding line. The researchers believe that these structures are human, confirmed by finding on one of the rocks of the relief image of an ancient creature – a Mastodon, extracted about 11,000 years ago. Mastodon is a popular herbivoring animal in North and South America, appearing about 35 million years ago and disappeared at the end of the last dead age.
Radiocarbon carved and dating style shows that Megalites was created about 9000 years ago, meaning about 7000 BC. This is duplicated by Stonehenge Anh. Mastodont's discovered image shows that the ancient American residents live next to these giants, which can focus on the legends or stone drawings.
Details of Stonehenge's origin are revealed
The modern depth of “underwater stonehenge” is about 12 meters. Granite blocks, perhaps, have been exploited in local quarters and weighs about 1.3 tons per one. These findings raise new questions about ancient civilizations and their knowledge about long animals.
