The Nemrut volcano erupted lastly in 1597, which led to the formation of Van Gölü.The caldera has a diameter of some 7.5 km; the altitude is around 2350 m. Slightly less than half of the caldera is formed by a crater lake, which is to 150 m deep (the photos below do not show the biggest crater lake). The slopes are partially covered with trees, but most of the caldera is rather sparcely vegetated. |
The many large boulders, in part obsidian, are good substrate for lichens. |
