Police investigators have no idea as to who or what is making a series of strange crop circles in Argentina.
The unusual pattern of wheat fields have appeared in the northern province of Salta in 2015, and the latest one was on a plantation in Chicoana.
Mercedes Casas, a crop circle investigator, said that the latest pattern has nine circles that begin big and get smaller until the last one.
The first circle has seven metres in diameter and gradually gets smaller until four metres with some interesting markings, Casas described. She added that lines connect the circles, approximately a metre wide and a few centimetres tall.
Another formation of crop circles appeared in Salta in February.
Mercedes believes humanoids designed these rings. These humanoids, according to Mercedes, are extra-terrestrial entities in the form of humans that appear tall and blonde.
A physics professor at Truman State University, Taner Edis, said these circles all fall within the range of hoaxes so far. Edis explains that he’s aware of claims of obscure natural causes or alien origin, but there’s no scientific evidence for such explanations.
