Kortik tepe maalesef Ilisu barajinin altinda kalmis. Google haritalarinda da suyun icinde gorunuyor. Ben sonbaharda sular belki alcalmistir en azinda gorecek birsey olmasa da nerde oldugunu gorebilmek icin gittim. Ancak birsey goremedim ve asil konuma da ulasamadim. Asagida fotigrafda ne kadar yanastigimi gorebilirsiniz. Piknik icin gidilebilir. Ancak burdan cikan harika eserler Diyarbakir Arkeoloji muzesinde ve muhakkak gorulmeli. Asagidaki resimdeki kap kirectasindan seramik degil.

This site is underwater of Ilisu dam. Google maps show it underwater. I went there thinking the water level could be low so that I could reach the exact location. But I couldn't get there. You can see how close I was from below photo. Its a very quite area for a lunch picnik. The very exquisite art pieces from here are at the Diyarbakir Archelogical Museum, they are a must to see. The photo shows a limestone cup from here, not seramic.
