Badgers discovered the burial site of 12th-century Slavic warriors and a Stonehenge cremation burial. The Lascaux cave paintings were discovered by four schoolchildren and a dog. The 5,000-year-old corpse of Ötzi was discovered when hikers happened upon in the Alps. The Rosetta Stone was discovered by French soldiers expanding their fort.
Many discoveries in archaeology have happened this way, by accident. But archaeology now has much better tools than badgers and lucky amateurs with shovels.
So Parcak developed a way to process satellite images with infrared in order to identify chemical changes in the soil caused by the activity of ancient civilizations. She quickly found patterns where there were previously none. With this technique, she located the long-ago path of the Nile and the probable location of this important city, which was the capitol of Egypt for 400 years during its important middle kingdom.
Looking for ancient sites this way has proved to be a boon for the study of ancient human civilizations.
Back in 2011, Parcak discovered more than a dozen lost pyramids and over 1,000 tombs and 3,100 ancient settlements in Egypt alone using this technique.
Last year, NASA archaeologist Tom Sever, archaeologist William Saturno of the University of New Hampshire in Durham, and researcher Daniel Irwin of NASA's Marshall Space Flight Center in Huntsville, Alabama used satellite images to locate several Mayan settlements that had been cloaked in deep jungle.
In June 2016, Parcak and archaeologist Christopher Tuttle, executive director of the Council of American Overseas Research Centers, used satellite imagery and drone photography to locate an enormous hidden monument in the well-known — and much visited — historical site Petra in Southern Jordan.
Last week, the Afghanistan Ministry of Information and Culture (MoIC), announcedthat it has used satellites to identify 5,000 ancient sites in that country over the past year. It's creating a map of the sites and hopes to use the information to protect the sites from looters.
But that doesn't mean that happy accidents are no longer needed in the quest to uncover the knowledge about prehistoric humans. In fact, Parcak is hoping to solicit the help of interested amateurs to speed up this important work.
