CART researchers have been busy, even during the recent heatwave excavating Operational Bunker (O.B.) remains. CART was granted exclusive access to this private and secret site, not previously recorded.
Many interesting features were unearthed and documented. These included evidence in the soil colour change and fill, combined with a clear line and termination of vertical corrugation indicating a metal shaft entrance.
Also unearthed was the unusual find of a section of ‘blind’ escape tunnel sat directly above the actual escape tunnel (storage?), and a length of cable exiting the shaft area (possibly linking to an Observation Post or for lighting?)…
Documenting new sites continues, can you help ?
