There are dunes of 114 metres high!

In Physical geography a dune is a hill of sand built by eolian processes (wind erosion, it blows the sand hill like it is). Actually there is more… Twenty-thousand years ago was the last ice-age. The North Sea was almost dry; you could walk from Holland to England. Approximately 1300 years ago the sea level was rising slowly. In the middle ages the climate changed, but the temperature was low and there were a lot of storms. A new dune complex was formed: the young dunes. During storms the dunes started to walk . They became higher with aid of helmet grass and the wind that throws the sand on the top of the dunes. Now the dunes are quite bigger. In France is a dune called Dune Du Pila, near Basin the Arcachon. They are the highest dunes of Europe. The dunes stretch 500 metres from east to west and 3 kilometres from north to south. The dunes are 114 metres high. The name of the dune is inferred of the word pilla. Pilla means battery in the language Gascons.
My opinion is that dunes are great. I like to run on it and roll of the dunes (It is forbidden to walk on it so don’t do the same as me!). My tip is: Take a look at Dune du Pila, I’ve been there and it is really cool, it looks like a desert when you’re standing on it. I haven’t roll of those dunes because my parents forbid that.
