ASPEX '91 Anglo-Soviet Pamir Caving Expedition
Seven British and eleven Russian speleologists aimed to follow up the 1990 exploration (90/36) of the 'Dark Star' cave in the Hodja Gur Ata massif in the Bajsuntai Khrebet region of Uzbekistan. The frozen streamway of 'Dark Star' had inconveniently melted, but useful exploration was made of 'Morning Star' and 'Prima' caves, as well as of various cave entrances along the 30km long rock wall.
