Hiked Naneghat last Saturday night. The picture is just before sunrise, taken from the base of the mountain (after we had hiked down). The 'V'-shaped wedge on the right is Naneghat, translated to English means 'tollway'. The pass was used as early as 200 BC and the cave on top has several inscriptions---some of which also suggest the oldest documented used of numbers.
