hmm ... maybe it's the same as tantalusschacht!
or maybe it was drill bolting - it was close enough the noise could be clearly heard is the relevant point and it was in the bunde, which I suspect is largely why we've failed to refind it despite presumably looking pretty close to it also that one may not be 2004-04 - I'm fairly sure it was 2004-0<something> but we seem to replace most references to the original number when a kataster number is allocated making it hard to really see what's what
aha, they seem to be in the cave index page:
so 2004-01 is the bivvy cave, 2004-03 is "dead gemse" which is back towards the 90s vintage top camp, -02 is really close to -01, -05 and -06 are over towards 111 and 112, -07 isn't it, -08 is more to the NW, -09 seems more E
so it's probably "lost" though it has a metal tag attached so if refound could be unambiguously identified.
