We trekked in the Tian Shan mountains in Kazakstan and Kyrgazystan in 2005.There are two videos here of the north and South Tian Shan Mountains. This was in the days before HD so the resolution is still DV PAL. Stage 2 features an exciting flight in an old soviet helicopter to the Inylchek base camp.
