Rigging over the top of an old rope. Second Pitch, Shuttleworth Pot.

Ropes rigged over each other. In this case, the second team had used poor etiquette, and rigged their rope (carabiner in the foreground) over the top of the first rope, even though they would be the second team to leave the cave. This offence will be remembered! Entrance Pitch, Pant Mawr Pot.

Rigging a rope on a pitch which already has a rope rigged on it, using the same anchors. This means that there will now be two ropes on the pitch, and subsequent cavers will need to ensure they use the correct one, especially if the ropes diverge into different routes part way down the pitch. The choice of whether to rig carabiners above ("over") or below ("under") the existing carabiners in the hanger, and therefore having the ropes appearing with the new rope in front or behind the existing rope, is a matter of etiquette; the team that is expected to derig first is usually allowed to have their carabiners over the other. This is easiest with permanent anchors such as P-hangers and naturals. With spits, the new hanger must be left clipped to the new carabiner, so that the derigging team can replace their own hangers with the new ones when removing their own.
