• CUCC 1987-08-30
• Reexplored (and a new sketch survey, see 1998 NotKH survey book) (Kate Janossy, Brian Outram) in 1998.
• Grade 3 survey in 1999 (Wookey, Andy Atkinson)

A steeply descending tube over scree (sometimes snow), initially 3m in diameter, leads down to a choke. To the right in a cross-rift 24m long (beware of loose rock here) is an audible connection to the surface (199c). The final section of the main tube has roof pendants, and ends with a rising sand floor over which the crawl becomes too tight. The second entrance (199b) is just up and to the left of the main one. None absolutely required, but 15m handline helpful for entrance, especially if snowy.
