this the closest anyoen has made it to border! Bother, they dont have a map on thier site!

Finally the moment we all were waiting for came - we were at the Indo-China
border - the reason for the expedition. The mountain appeared - it stood boldly
in black, in stark contrast to its pastel shaded peers.In shape of a Trishul (Tri-pointed weapon used by Hindu God Shiva), it gives birth to the name
Chusul. Incidentally, the name of the regiment that serves the nation in
this region is also Chusul. It took sometime for the thought to seep in that
2 kilometers away from where I was standing, was China.
