The Forbidden city is a fine boulder-strewn chamber of fine +dimensions, reminiscent of Knossos in Kaninchenhöhle, sloping +upwards to the North west and the exit into the Gobi Desert. Near the +lowest point, (below and to the right of the Carry-on up the Khyber +entrance) is a rocky crawl which leads into a wide but choked space +below the Carry-on up the Khyber passage. There is at least an aural +connection up to that passage. In the Southern corner of The Forbidden +City is [C2007-204-?? X].
+ +A large (8m wide) bouldery passage leads off from the upper end of The Forbidden +City heading steadily uphill and north-north-west. There is one +notable climb up a large sloping rock which needs a little care. After 90m a passage leads off +to the right ("Silkworm"), and then the passage drops to being a crawl +to reach a complex T-junction after 110m. To the +left is Enter the Flagon. To the right a +rocky passage carrying a strong draught leads downhill and south to join up with +Silkworm after 20m at a 90left corner. This
+ +Beyond here the passage is full of unusally fine light-coloured +sand, from which the area gets its Gobiu Desert name. It is +comfortable but not particularly large, with some crawling and +stooping where the sand fills much of the passage. [C2007-204-?? C] +and [C2007-204-?? B] are along here.
+ +After 70m an aven 20m+ high is reached where water can be heard at +the end of the rift [C2007-204-?? C]. The strong breeze continues down +the passage ("Crouching Tiger") which now gets rather smaller being +stooping and crawling all the way. It winds for 90m to a short 2m drop +into a small chamber where there is a 4-way junction. A crawl leads off +uphill to the left (East) with a strong outward draught[C2007-204-?? +A]. A keyhole passage comes in from the South [C2007-204-?? +A], up which most (all?) of the draught goes. And a low passage heads down to +the West [C2007-204-?? B].
