peashooter85:mapsontheweb:About 7,000 years ago, a vast lake spread hundreds of square kilometers across north-central Africa. Known to scientists as Lake Mega Chad, it covered more than 400,000 square kilometers (150,000 square miles) at its peak, making it slightly larger than the Caspian Sea, the biggest lake on Earth today.
