>>2843789>>2843786>amateurishMany experienced climbers don't bother tying knots at the ends of their ropes when abseiling because they know (or think they know) the rope is long enough.
They know they should tie knots, but they don't bother out of laziness or convenience. It's not really a sign of amateurishness.
>>2850204No. Usually there is an established anchor up there, like a tree with slings around it, or a proper drilled metal bolt with a metal loop for your rope.
For abseiling the rope is doubled and you descend on two strands of the rope. When you are down you can pull on one of the strands and the whole rope comes down.
There are also some setups that allow you to create a temporary anchor that comes down with the rope when you pull on a third separate strand or pull on the main rope a few times in a certain way.
