Tian Shan (Chinese: Heavenly Mountains) is a mountain range in northwestern China and eastern Kazakhstan. According to inscriptions written on the very portal that sealed the entrance chamber to the Infernal Machine in Babylon, if one were to seek out the Machine's four vital parts, one should begin the journey at the "heavenly mountains." In 1947, Indiana Jones correctly interpreted this to mean the Tian Shan mountain range. After infiltrating a Soviet-patrolled border region and rafting the whitewaters of the Tian Shan River, Jones arrived at Shambala Sanctuary, where the first piece of the Machine was kept.
