The Wet Period
Next stop, the Green Sahara! Although it may appear to be a giant box of sand, the largest in the world at that, the Sahara Desert in North Africa is far from dead! Not only are there still cultures and kingdoms that cut right across this heat haven, but it was once full of grassland, monsoon rains, and lush forests. With vegetation and water comes animals and people with their sophisticated astronomical technology, advanced mummification techniques, and dazzling rock art. All you have to do is dig deep enough and you’ll find an entire historic world hidden beneath the sand.
