The White Lady

Rapid Evolution of an Arch

Arch evolution can occur over thousands of years, but La Dame Blanche (The White Lady) in France consisted of a crumbly clay-like rock and evolved from youth to maturity to collapse in the course of just a few years.

The photo below taken by Albert Zwinkels in 2009 shows a small, young opening.
