The Nile flowed through an area of eastern Libya at what we now call Wadi al Hamim and Wadi al Maqar and into the Gulf of Sidra, which is more than 1,000 km (620 mi) west of the river's present mouth. When the water level rose at the end of the last ice age, most of the water began to flow through the current riverbed. The current riverbed begins near the present-day city of Asjut in Egypt.
