Had a pleasant trip into Switzerland. We travelled along the Rhone valley to Sion and then up another valley to the Grande Dixence Dam. We spent the afternoon visiting inside the dam wall and then taking the cable car to the top of the dam wall and having a lovely, if not a tad windy, stroll around.
For those who are interested here are a few facts:
At 285m, it is the tallest gravity dam ever built. The wall is 15 million tonnes, making it heavier than the Great Pyramid of Cheops. It took 10 years to build. At the lowest point it is 200m thick. It retains 400 billions litres of water and is the largest artificial lake in Switzerland.

 Very smoggy view of the Rhone Valley.
