While I was doing Wainwright's Coast 2 Coast hike a few years ago and I stayed overnight in a b and b I noticed a big huge boulder the size of a small house perched on top of a large hill/small mountain. This was in a small village in Cumbria/The Lake District in the UK. Can't remember the name of the village.
There were several small farms and farmhouses located beneath it. I thought to myself I would not be able to rest easy with that kind of threat overlooking me. It would not take much to shake that boulder loose. Then you think of the logistics of getting rid of it. Blow it up? Then big pieces come rolling down the hill. Interesting scenario which this video reminded me of....
