Kite-like structures in the western Sahara Desert.

Since 2010 numerous 'kite-like structures' have been discovered in the Middle East, and more recently the Libyan Sahara. These are prehistoric megastructures, interpreted to have been gigantic traps, into which Animals could be driven by hunters. The vast nature of these structures makes them almost impossible to detect from the ground, with almost all being detected from satellite imagery. Most of these structures are in remote desert regions, and to date, very few of these have been visited or investigated by archaeologists, leaving us with little idea about their age or the people who constructed them.
