Mattertal
The Mattertal is a valley that was made by a glacier (a slowly-moving river of ice) moving down from the mountain. This can be seen from the deep U shape of the valley. (Valleys made by a fast-running stream are V-shaped). Because the sides of the valley are very steep, there are often landslides. One can be seen in the photo taken near Randa village. Many houses in the villages are called chalets. These can be seen in the picture of Täsch village.
