; Extra info from John Cordingley's dive log via email from John to Becka on 24.11.10 - Dive made on 28th August 1982
; The sump runs back under the approach passage. The passage is coated with lots of fine silt which makes it very difficult 
; to stay ahead of the clouds. After a descent to -3 m the passage rises to an airbell 6 m from base. 4 metres beyond is 
; another smaller airbell. At 12 m from base in total ("base" means the centre of the just-submerged rock lip where the 
; underwater passage goes back under the approach passage) the passage is suddenly blocked by deep silt banks. 
; The underwater passage is straight and the trend was recorded as 53 degrees magnetic.
; Becka has used this info to add in some sump legs
