This reminds me of one of the episodes of the documentary series "Endangered Civilizations". From the description[1]: > 9. The Books Under the Sand > During the time of trans-Saharan trading, its strategic location along the caravan route enabled it to prosper. It was also the gathering place for the pilgrims from western Sahara as they began their journey to Mecca. It had already attained the position as a prestigious economic and spiritual center. Chinguetti was considered the capital of the "Land of the Moors". In the episode, they reference and show a lot of very old texts. If I remember correctly, they mostly came from the days when the area was replete with trading activity, around the 12th or 13th century. One of the things they discuss in the episode is the fact that there aren't enough researchers/scientists that are studying them, so many of the books end up being inadvertently destroyed or buried under the always-shifting sands. While I was watching the show, I remember thinking how awesome it would be to have some sort-of machine that you could point at the ground and be able to just see what's buried deep underfoot, for a wide radius. There's so much history in that area that is just completely inaccessible to us because of the climate and geography.
