Worth realising now while I remember that I have not credited the passages which I have stolen from other surveys.
Marniosa Entrance to sump 1, Plan view has almost exclusively been stolen from the LUSS surveys (1975-1979), this does not include Extra caverns, surveyed by Phil, Joe and Howard (2018-2019).
Sump 1 to sump 2, surveyed SWCC 1986, Colin Boothroyd, Ian Rollands, Steve Jones, Fran Hampton, Rich Barker and Rob Parker.
Beyond sump 2 was surveyed by Josh Bratchley (2017-2018) and Rob middleton (2018).
