Mount Tendurek in Diyadin

You're standing at Mount Tendürek, a volcano in the far east of Turkey, close to the border with Iran. Have a look around. Notice how gently the slopes rise? That's why it's called a shield volcano: the mountain looks like a shield lying flat on the ground. Don't be fooled, though, because it's huge. Its lava covers around 650 square kilometres, and the summit rises above 3,500 metres.
