Glacial valleys in the European Alps.
The paths taken by glaciers in the most recent Worms glaciation, that ended around 10,000 years ago, are clearly visible in this image of the Alps taken from the Space Station. Mist fills the U shaped vales, rising from the braided rivers flowing along their bottoms. Paths of subsidiary glaciers joining the main ones are also visible at the sides of the larger valleys. The dendritic drainage in the higher areas above the valleys results from rainfall and snowmelt during the current Holocene era.
We did a recent post on these valleys, illustrated with a beautiful photo of one seem from ground level at http://tinyurl.com/nhr2735.
