What is a tyrolean traverse?

Answer 1

Tyrolean traverse is a mountaineering maneuver that involves lassoing a pinnacle round and traversing to the top and back. It has been used in some first ascents. The ropes can be crossed either by getting on top of the two ropes and pushing them apart with hands and feet, or by hanging below the ropes and hooking a leg over the top. It often makes for spectacular pictures and stunts. Modern climbers usually use a harness and a carabiner or a pulley, to make it easier and safer. Tyrolean is often used as a misnomer when referring to a "highline," a rope stretched between two high points. It is often used as a retreat method from isolated pinnacles.
