This is a fun fact Friday mini episode covering a little bit of information about the Nazca Lines.
The Nazca Lines are massive geoglyphs created in Peru around 400-600 CE. While there is a lot that is uncertain about them, the most common theory is that they were created for religious reasons. While the designs are absolutely huge with lines that span several miles, the full design is not really visible from the ground so they were not widely known until the age of aviation. In 1930 the designs were rediscovered by people flying in a plane over Nazca and they have been studied and speculated about ever since.
