A remarkable fingerprint of the (near) geological past is U-shaped valleys. Intuitively, it is not that hard to imagine that rivers, constantly transporting smaller rocks and debris etc., may carve solid rocks over time, forming deep and rather narrow V-shaped valleys. That frozen ice do the same is, at first, less obvious. On the other hand, with a layer of 2-3 (or more) kilometres of ice on the landscape, slowly moving downslope and towards the sea, one can understand that tremendous frictional forces are at work. The resulting U-shaped valleys are beautiful, and we have quite some examples in Norway.

The attached image is from an almost perfectly U-shaped valley, Isterdalen, in North-Western Norway. Yes, I simply loves these valleys!

The photo was taken early in the morning in June. I joined a group of photo-entusiasts, and we had been shooting landscapes, farms and whatever the previous day and throughout the night. On the way back, heading for a upcoming workshop and (very) short of time, I kindly asked the driver to make a quick stop. With the Mamyia 7 body loaded with infra red film, it only took a few minutes to make some exposures. The other fellows remained in the car, cold and tired after shooting and, understandably, eager to reach the workshop in time...

In the end - at least based on my very subjective judgement - this short stop, with a single photographer in action  - made the night...
