Noorderhaaks on the left of the picture
Noorderhaaks, also called Razende bol (Raging ball in Dutch), is a Dutch sandbar in the North Sea, a few kilometres west of the Marsdiep which separates the island of Texel from mainland Netherlands. The sandbar covers an area of around five km², although the exact area varies due to tide and the dynamic nature of the area.
Being relatively untouched by man, the sandbar has become a valuable location due to its presence of several kinds of seabirds, and seals.
The sandbar is slowly moving eastward towards the Marsdiep and the Molengat, at a pace of around 100 metres a year.
The sandbar is visited by day trippers, and is also being used as a training ground for the Dutch navy and air force.
