I missed this story at the time, but it is worth highlighting here. Back in early August, golfers at the Matterhorn Golf Club in Taesch, Switzerland faced a slightly unusual hazard when a boulder fell from an adjacent mountain to land on one of the greens. The oobgolf.com website has the best set of images, from which these are taken:
In the comments below the article, several people are confused about how it ended up in the middle of the green. I would suspect that the boulder was both bouncing and rotating – in this case the tabular shape of the rock would create a very stable motion (a bit like a wheel bouncing down a slope). This would also be why the crater has that elongated shape, and why the boulder has bounced out of it.
