Abseiling

Abseiling (or ; from German abseilen'to rope down'), also known as rappelling (or ; from French rappeler'to recall, to pull through'), is the controlled descent of a steep slope, such as a rock face, by moving down a rope. When abseiling, the person descending controls their own movement down a static or fixed rope, in contrast to lowering off, in which the rope attached to the person descending is payed out by their belayer.
