During an investigation by scientists of the NOAA Ocean Exploration, they found a mysterious line of holes at the summit of an underwater volcano north of the Azores at a depth of 1.7 miles in the Atlantic Ocean.
An organized network of holes drilled into the ocean floor was discovered by scientists investigating a submerged mountain range in the middle of the Atlantic.
Photos taken after the discovery on July 23 show how the dots connect to form nearly straight trails, designs, or lines.
NOAA Ocean Exploration is still unsure about how to explain it.
“We observed several of these sublinear sets of holes in the sediment. These holes have been previously reported from the region, but their origin remains a mystery,” NOAA Ocean Exploration reported.
“While they look almost human made, the little piles of sediment around the holes make them seem like they were excavated by … something.”
