いにしへのサハラ
すごい!
<7000〜3000BCのサハラは、砂漠どころか草原で、浅い湖があった。
昔の人は、その水路を移動に使っていた。
今も、乾燥した河床や岩壁画が残っている。>

The Saharan Mega-Lakes during the Holocene Wet Phase
Between c. 7000 – 3000 BCE
the Sahara was far from the desert it is today.
It was covered in grassland and dotted with shallow lakes.
Ancient humans used its waterways to travel up through Africa.
Its legacy remains today in rock art and dried riverbeds.
This map is a speculative reconstruction of this lost world.
