Mundafan

About

Mundafan was a former lake in Saudi Arabia, within presently desert-like areas. It formed during the Pleistocene and Holocene, when orbitally mediated changes in climate increased monsoon precipitation in the peninsula, allowing runoff to form a lake with a maximum area of 300 square kilometres (120 sq mi). It was populated by fishes and surrounded by reeds and savanna, which supported human populations.
