Boybuloq

Boybuloq (also known as Boy-Bulok and Boj-Bulok, Boybuloq) is a limestone cave in Uzbekistan, the deepest cave in Central Asia and all Asia except its western part. The cave is 1,523 metres (4, 997 ft) deep and 19,900 metres (65, 300 ft) long with the main entrance at an elevation of 2,647 metres (8, 684 ft) above sea level. It is situated at the edge of Baisuntau mountain ridge, the southern spur of the Gissar Range, in the southeast of the country. The nearest village is Dehibolo (in Russian), to the northeast of Boysun. The cave developed in the covered karst of Upper and Middle Jurassic limestones, in monoclinal strata, in the preserved wing of an anticline. The thickness of limestone strata is 200–350 meters. Contrary to most limestone caves, it was not formed by water precipitation penetrating from the surface, but, as the soluble rock is covered by insoluble strata, by condensation. Hence the cave consists mainly of very narrow passages which descend along the incident angle of strata, from time to time interrupted by vertical shafts, no deeper than 30 metres (98 ft), and ends with an impassable siphon. It was explored by Russian cavers since 1984, in the framework of Ekaterinburg Speleo Club (SGS) and the Assoiation of Speleologists of the Urals (ASU), with the participation of cavers from Italy, Great Britain, Slovakia, France, and Swit
