In 2021, Jacob Geersen, a geophysicist with the Leibniz Institute for Baltic Sea Analysis within the German port city of Warnemünde, took his college students on a coaching train alongside the Baltic coast. They used a multibeam sonar system to map the seafloor about 6.2 miles (10 kilometers) offshore.  Analyzing the ensuing photos again within the lab, Geersen seen an odd construction that didn’t seem to be it will have occurred naturally.

Additional investigation led to the conclusion that this was a artifical megastructure constructed some 11,000 years in the past to channel reindeer herds as a searching technique. Dubbed the “Blinkerwall,” it is fairly probably the oldest such megastructure but found, in keeping with a brand new paper printed within the Proceedings of the Nationwide Academy of Sciences—though exactly courting these sorts of archaeological constructions is notoriously difficult.

As beforehand reported, in the course of the 1920s, aerial images revealed the presence of huge kite-shaped stone wall mega-structures in deserts in Asia and the Center East that the majority archaeologists imagine had been used to herd and lure wild animals. Greater than 6,000 of those “desert kites” have been recognized as of 2018, though only a few have been excavated. Final yr, archaeologists discovered two stone engravings—one in Jordan, the opposite in Saudi Arabia—that they imagine characterize the oldest architectural plans for these desert kites.
