    It is intended to add rigging guides to the descriptions for each pitch -series in CUCC's major caves - these will be graphical, and based on sketch -rigging guides currently in various survey and log books. Look for the -rigging guide link in the descriptions. To help people add rigging -guides to the cave descriptions, it is essential that rigging -guides are drawn for any new rigging or rerigging each year.
