A Prehistoric Site in Western Macedonia and the Dorian Invasion

The geographical configuration of Western Macedonia, resolved into its simplest elements, may be described as consisting of two parallel depressions, running roughly north-west and south-east, and separated from one another by a mountain range, the whole area being itself entirely enclosed by mountains. The eastern of the two depressions has a northern and a southern half. The northern half is the valley of the upper Černa, the southern is composed of the low land round the western end of Lake Ostrovo, which is connected by a narrow corridor with the valley of the middle Haliákmon. Similarly, the western depression has two well-defined areas. The northern is the basin of Lake Ochrid and the plain of Korytzá; the southern, the basin of the upper Haliákmon and its tributaries.
