The northernmost point in India is called Indira Kaul or Col. The name comes from the world col or mountain pass. Thus the Indira Col is a mountain pass which is located on the Indira Ridge and is located in the Karakoram Range. It is a very unique place as the apex and summit of the mountain pass is where three countries come together and they are India, China, and Pakistan.
There are several surrounding passes on the Indira Ridge that carry that Indira Kaul name but today there is only one that is recognized as the main Indira Kaul. It has been visited by several explorerers over the years with notable explorations of the area being done in 1981 and in 1988 with both explorations being done by natives of India. This is also an area that has several tribes and indigneous peoples in constant dispute with each other over rights to territory and land that is situated around Indira Kaul.
