It is true that to go from Ur to the Halys River, one would travel more than 600 miles northwest.
The Halys River today is known as the Kizihrmak River. It is located in Anatolia, Turkey. It is the most important river in the region. It is a long river with a length of 1150km. It was an important location in the times of the great ruler Sargon of Akkad, who united the regions of the north and south Sumer and expanded the city-states far beyond Mesopotamia.
