5. Glacial river with rock flour (250 m.a.s.l.)
|
At this locality we look down from a morainic mound towards the confluence of two streams. The stream to the right (Tverrelva) comes from the waterfall on the northern side of the valley. Its water runs clear and contains little fine material. In contrast, the stream to the left (Steindalselva) is full of rock flour, which gives the water a milky appearance. Rock flour consists of ground-up mineral particles washed out from the glacier. It is clear evidence that the glacier is continuously grinding away at the bedrock. |
