Old photos I know, but I can't find any others online and thought this might be of interest to some. The post is securely locked now and seems to be used for some sort of telecommunications with a large parabolic dish antenna mounted on the ventilation pillar.
Opened in December 1959 this was a master post and also one of 6 seismograph stations used in conjunction with the nuclear test ban. Because of their important role these posts were not formally decommissioned until 1994. A high fence was installed in the early 1980s following anti-nuclear protests from students at the neighbouring University.
When we visited, the post was flooded with about 1½ -2' of water. We didn't stay long because of the high concentration of hydrogen sulphide (stinkdamp) which is highly toxic in anything but the smallest of doses.
Surface features
Hatch with unidentified box attached
Monitoring room - the purpose of the green cable is unknown but probably has something to do with whatever the post is now used for.
Instrument table, fixed survey meter and bomb power indicator mount with more mysterious green cable.
Instrument table and cupboard
Wiring and GPO Junction Boxes (apologies for blur)
