So what have we learned so far?
All new bits of cave have the potential to contain important scientific 'stuff'.
Cavers on the whole are not best placed to decide what is or is not potentially important 'stuff'. (As has been described on previous posts on this thread - we do not realise the true potential for stratifed mud / clastic sediments etc. Instead being guided blindly by those whores of the underground known as pretties).
Cave scientists are the only true people who can distinguish between potentially important 'stuff' and actual important 'stuff'.
To preserve the potentially important 'stuff' until such time as a bonafide cave scientist can impartially assess and establish as to whether said 'stuff' is important and if so, ascertain it's true significance (or lack thereof) - cavers will need to be excluded from the area to avoid contaminating the area under observation.
Now we all know that some cavers are little monkeys, and that when told not to do something will, as is human nature, go and do it anyway. The potentially important 'stuff' will need to be protected from these people.
There are also other types of caver; for example, those who assume the high moral ground on such matters and believe that their caving style enables them to pass over/around/underneath any potentially important 'stuff' without the slightest possible chance of contamination, including that from conservation tape. The potentially important 'stuff' will need to be protected from these people too.
The logical conclusion it would seem, is that any new stretch of cave passage must be assessed for potentially important 'stuff' by a bonafide cave scientist, before any other caver whatsoever is allowed to enter.
As has already been alluded to above - some cavers obviously can't be trusted to do this, whilst some believe they are gifted with the attributes of non-contamination.
Using the reasoning used so far for placing the gate in this section of cave passage, from now on, shouldn't all new sections of cave passage be gated and access denied - even by the discoverer's, until such time as the true scientific value of the potential 'stuff' has been scientifically realised?
Alternatively, we could put some sort of perspetive on this.
Massive loss of life from flooding in Pakistan - millions with no food or shelter - widespread disease imminent.
For f*cks sake - take the bloody gate off, nobody go in and trash it (and if they do will anyone die?), and everyone just get a life.
