NCC Shafts - Alan Brentnall
A small party of four (Lee Langdon, Ade Pedley, Christine Wilson and myself) went into NCC Shafts with the intention of sorting out a better rig for the 2nd pitch. When this pitch was originally bolted, the few bolts which were available left the rigger with a long tension traverse along a gulley, a fall from which might have had serious consequences. The new solution is a high deviation from a P32 above and part way along the gulley which lands the caver nicely within a couple of metres of the rebelay. This new deviation should not be confused with another existing deviation lower down which is, in fact, the tied-off end of a rope coming down from Mummy Inlet - this rope should really be removed along with some of the other older ropes in NCC Shafts.
Here is a rough sketch of the new set-up, complete with pitch lengths etc - this will form the basis for the NCC Shafts Topo in the 12th edition of the CCPC Rigging Guide when it is published:
