Kongka La is the low ridge pass in the Himalayas (the blue oval in the map). It is in the disputed India-China border area in Ladakh. In the map the red zone is the disputed area still under Chinese control in the Aksai Chin area. The Chinese held northeastern part is known as Aksai Chin and Indian South West is known as Ladakh. This was where Indian and Chinese army fought major war in 1962. The area is one of the least accessed area in the world and by agreement the two countries do not patrol that part of the border. According to many tourists, Buddhist monks and the local people of Ladakh, Indian Army and Chinese Military maintain the line of control. But there is something much more serious happening in this area.

Makes one wonder just how extensive the underground structure of the world is. Imagine an underground network of tunnels connecting cities all across the world.
