The lower part of the valley, at altitudes below 3,000 metres (9,843 ft), is one of the most agriculturally productive parts of Ladakh with two crops a year being harvested, watered by the run-off from the very heavy winter snowfalls, and even plantations of willow and poplar trees making it a relatively lush and very attractive area, but around Rangdum the landscapes are stark, flat moorlands ringed by arid crags. The spikey white topped mountain peaks of the Nun-Kun massif, topping 7000m, are visible from several places in the valley.
