Shyok Valley, close to Nubra, is a valley of the Shyok river, which originates from the Rimo glaciers. The Khardung La pass, highest motorable road in the world, on the Ladakh Range which is on the north of the town of Leh, the gateway to the Shyok Valley. The towering ranges of the valley are a visual delight with vegetation on its borders. Shyok river is also known as the river of death, probably because its route is a difficult one, not opted by many. This river is a tributary of the river Indus. The Nubra river, originating from the Siachen glacier, also behaves like the Shyok. Before Tirkit, the SE flowing river Nubra takes a NW turn on meeting the river Shyok. The similarity in the courses of these two important rivers probably indicates a series of paleo fault lines trending NW-SE in delimiting the upper courses of the rivers. The importance of the Indus and the Shyok rivers is in the deposition of the thick Quaternary sediments—a treasure trove for geology researchers.
