Fingers within the Pangong Tso Lake

Chang Chenmo is the name of barren mountains situated at the northern bank of the lake which extends out into major spurs into the lake that are called fingers by the Army. China claims that the LAC passes through finger 2 while India believes it to be passing through the finger 8. Both the countries control the land on their respective sides only up to finger 4 where the major confrontations have been happening in the recent past.

Officially, the McMohan Line defines the border between India and China. It was created by the British Indian Government as an agreement between India and then Tibet. China always objects to the whole border settlement as it claims that the agreement is false because China wasn’t part of it rather Tibet was.
