Karacadağ is an extinct volcanic mountain located in the Southeastern Anatolia Region of Türkiye, situated between the southwestern part of Diyarbakır and the northeastern section of Şanlıurfa. Notable for its shield-like formation, Karacadağ is a prominent geomorphological and climatological feature that defines the natural landscape of the region.

Geomorphology and Volcanic Structure
Karacadağ was formed during the Pleistocene Epoch (approximately 2.5 million years ago) through the successive accumulation of basaltic lava flows. Unlike the typical conical volcanoes, it exhibits a “shield volcano” (Hawaiian type) structure due to the high fluidity of its lava. The lava plateau, with a diameter of approximately 120–130 km, extends eastward to Diyarbakır, westward to Siverek, and southward to Viranşehir. The highest point of the volcano is Kollu Baba Hill, with an elevation of 1,957 meters. The volcanic mass is intersected by east-west-oriented parallel fault lines.
Ecology and Natural Resources
The northern slopes of Karacadağ, particularly those facing Diyarbakır, are covered with a thin soil layer and are suitable for agriculture. These areas are also home to sparse oak (Quercus) communities. Other parts of the mountain are dominated by large and small volcanic rock fragments. Springs that emerge from the foothills feed into some tributaries of the Tigris River and provide drinking water for Diyarbakır and Siverek. Radial valleys extending from the mountain subdivide the volcanic mass into distinct morphological regions.
Climate and Geographic Influence
Karacadağ forms a natural boundary between the Diyarbakır Basin and the Şanlıurfa Plateau. To the north lie the Batman–Dörtyol Crude Oil Pipeline and the Diyarbakır–Şanlıurfa highway. Toward the southeast, the terrain descends to the Harran Plain and desertified zones near Viranşehir. The Adıyaman Mountains and the Atatürk Dam Lake, located in the northwest, contribute to microclimatic variations that influence the broader regional climate.
Karacadağ Ski Resort
Situated within the Siverek district of Şanlıurfa Province, approximately 60 kilometers from the district center, the Karacadağ Ski Resort is the only ski facility in Southeastern Anatolia. Open from late November for about four months, the resort features a 700-meter ski run that caters to both amateur and professional skiers. The facility also includes service buildings and a café. The resort attracts significant weekend visitation from nearby provinces such as Diyarbakır, Adıyaman, Mardin, and Gaziantep.

Historical and Cultural Context
The broader Şanlıurfa region surrounding Karacadağ is one of the oldest continuously inhabited areas in human history. Notable heritage sites such as Göbeklitepe, Soğmatar, and Harran are located in proximity to Karacadağ. Archaeological evidence suggests that settled life and agricultural activities in the area date back to prehistoric times.
