Recently, I found this map of Africa's paleolakes in the Imaginary Maps reddit:
Finding this map was mere coincidence, but this map definitely interests me. Now there have been multiple what-if, worldbuilding and alternate history scenarios set in this Sahara with freshwater lakes instead of nothing but rock and sand as far as the eagle eye can see, but I would like to take this a bit further.
Finding this map was mere coincidence, but I have been imagining an alternate Earth in which the Tethys Sea never closed off (in translation--erasing Turkey, Iran and the Arabian Peninsula from physical existence, turning the Mediterranean, Black and Caspian seas into one.)
In advance for anyone who'd like to know, I'd like to bring up a backstory on the lakes of this Sahara. It's simple--they are where fault lines sink to the aquifers of North Africa, making the lakes similar to the Mexican cenotes, flooded openings of underwater caves.
Combining all of these details accumulate into one question--would we still have a Sahara Desert of one form or another?
