Cross passage

Cross passage or traverse is a term from climbing and describes a horizontal section in a climbing route . In a transverse passage, you do not climb vertically upwards, but move around sideways without any significant gain in height.

In multi-pitch routes in traditional climbing or alpine sport climbing, cross-corridors often prevent the rope team from simply retreating from the climbing route by abseiling after the climbers have overcome them , because in order to get back to the lower part of the route, the cross-corridor has to be climbed back. Another special feature in cross aisles is that the second climber , like the lead climber , can fall. The pendulum falls that occur are also considered more dangerous than normal falls. Therefore, routes with larger cross aisles are not suitable for the subsequent ascent by a significantly less powerful climbing partner.

Special cases of the traverse are the cable traverse and the pendulum traverse , both of which are assigned to technical climbing .

Well-known traverses are the Hinterstoisser traverse in the north face of the Eiger and the traverse in the climbing route "Große Micheluzzi" on Piz Ciavazes in the Sella group of the Dolomites .

The bouldering crossways , which are also known as traverses, represent a special type of traverse. As is usual in bouldering, the boulderer climbs above the ground at jump height without safety. Such bouldering crossways, some of which run along the feet of the wall, can be very long.

From a physiological point of view, cross aisles in sport climbing are less stressful than vertical climbing with the same difficulty in terms of the maximum and average heart rate required for this. This can be explained by the lower energy expenditure for locomotion.
