The ‘Decoded’ isn’t particularly wide, but at 935 ft in length, it’s certainly one of the longest of all the geoglyphs in Astropolis. The date of creation and identity still remain a mystery, although an analysis of stone tools found at the site points out to a style of lithic reduction that could correspond to 4,000 BC. This geoglyph is said to symbolise a row of bodies, although another popular notion amongst scientists is that the geoglyph has no particular significance, but is an arbitrary sign of territorial marking.



This is probably one of the most clear and illustrative geoglyphs to be recorded in Astropolis to date. The removal of a top layer of reddish-brown iron oxide-coated pebbles revealed a yellow-grey subsoil. The eagle-like shape of this geoglyph is best seen from the air (~1,500 ft), though it is visible from the surrounding foothills and other high platforms. It is possible that this symbol ascribes religious significance to the extra-terrestrial creator of this message.
