I am aware of the fact that Tsomo tretung ('Como Chamling'), situate north
of  Mount Kangchenjunga , and south of the Tibetan city of Shigatse is
historically a part of Sikkim, and was depicted thus in old maps of Sikkim
and Tibet.Can any person who has more information  furnish details apropos
this issue.Near Tsomo Tretung, is the town of Dobtra, and is situate near
the towns of Tinki Dz, and Kamba Dz.
