The draught issues from a too-narrow rift roughly below the entrance. The top of the rift has a large rock wedged in. This can be rocked if pulled very hard. Perhaps it's worth removing to see if the rift is wide enough at the top? It's definitely wider beyond the rift. 2004 log book plateau/2004-02/2004-02.html plateau/2004-02/2004-02.html
