The hole believed to be 160 was unmarked until tagged in 1998 "1623 160 CUCC 1988" on flat limestone 1m east of entrance. This had been relocated in 1996 and was then thought to be 159, but latter was found marked in 1998.
This used to have fixed point
1623.gps00.160 to locate it, but this seems to have been removed fromt he fixedpts list.
