evidence: That perception changed a few years later. In the late 1970s India woke up to the fact that publications abroad, including U.S. government documents, were carrying maps that showed the LoC extending northeast from NJ 9842 to the Karakoram Pass. In other words, the Siachen Glacier was appearing in maps as part of Pakistani territory. Besides, it learned that Pakistan was permitting Western mountaineers access to the Siachen and the ridges flanking it, quietly establishing its claim over the area. [...] The two countries base their claims over the glacier on different interpretation of the words "… thence north to the glaciers" in the 1949 and 1972 Agreements. To Pakistan it means a straight line from NJ 9842 in a northeasterly direction to the Karakoram Pass, giving it control over the Siachen Glacier. India argues that from NJ 9842, the boundary line should run through the nearest watershed, the Saltoro Ridge, which means that the glacier is rightfully India’s.
