This picture actually shocked me when it first came up. Wow.
Actually, it was not that dagerous. An old guy was sitting in the shadow when I came up. I stood for some time taking pictures, when he told me to sit down and crawl on my butt - so that my feets ended up like on the picture. Then when in position reach out with the camera to take the picture.
So - its kind of a trick foto, but it looks very scary!
