"Lost" Fortresses of Sahara Revealed by Satellites

I chose this article because from the title it looked very interesting since it was about a very mysterious civilization. I know this article is valid because it is from a very trusted website. Also it was on other websites like the "Heritage Daily" and other news corporation websites. It is fascinating how ancient civilizations can be very advanced in technology for certain reasons. I thought it was intriguing how they used the irrigation systems to grow grass in desert areas to use for crops. They built underground canals so the water would not evaporate since they were in a desert. It must have been difficult to build this because it took an estimated 77,000 man-years to build this. This proves how smart civilizations can come up with very odd ways to do stuff that is hard to do, like plant crops in a desert. It was difficult to discover these sites because the researchers ran out of money, the sites were in the middle of the Sahara Desert and the war in Libya stopped the researchers for a while.
