They are visible only from surrounding mountains or from the air, which gives them an aura of mystery. Now, a group of researchers from Argentina and Spain will study a structure that could be a geoglyph discovered last year at about 3,000 meters above sea level in the Tigre mountain range (Argentina) and which was found by mountaineer Carlos Gobbi while consulting Google Earth. A joint expedition will attempt to examine it in situ in December.
