There is an explanation- Dark Matter. There is a new theory about supermassive high energy particles that exist in another dimension and only communicate with our plane by the force of gravity. Their distribution is non-uniform, that is, like visible matter, they cluster. So it is clear that some crags have higher densities of dark matter associated with them. In fact, these particles know your name. Some pull with greater force on Distel, while others pull more intensely on erik.
