Ok I'll bite
What is your special interest and do you have any fun facts about it?
ok there's this thing in the sahara desert called the Richat Structure. It's 30 miles wide, it can only really be seen from space. it just looks like this giant fucking EYE in the middle of the desert. i came across it by accident while just scrolling around on google earth like a decade ago and went HUH???? cause it's so creepy and weird so then I got obsessed.
basically scientists think it's a highly eroded dome and not an impact site or man-made or anything. a bunch of different kinds of rock are exposed in concentric rings. however, it is an archeological site and they've found a bunch of Archeulean tools and artifacts in great condition there (like stone axes and stuff from homo erectus). archeologists think this area was used in tool manufacturing.
im just totally fascinated i think it's cool as hell
