This photo showing a scenic walled walkway was was taken in Saumane (Vaucluse), France on November 6, 2005. The walls are composed of a type of sandstone, which in France is referred to as "mollasse." It's actually a soft sandstone formed during the Tertiary Period (about 65 to 1.8 million years ago). These highly stratified formations are evidently unique to Europe and reveal the ebb and flow of ancient tides.
