Geology site description:
Ancient beach ridges are visible in the landscape near Spaarnwoude. These beach ridges date from the period between 5000 and 2000 years ago. Due to a delay in the coastal sea level rise during this period, the land could further expand to the west. In North and South Holland a series of parallel beach ridges were formed. Many beach ridges have been leveled or fully built and cannot be recognized in the landscape anymore. In Spaarnwoude however they are still very visible. The shoreline of Spaarnwoude is about 5000 years old.
Because of the forming of the beach ridges, the inland was increasingly cut off from the sea. Peat began to form in the area behind the beach ridges, sometimes with clay intervals when there was more influence of the sea. The peatlands in western part of The Netherlands have originated in this way.
Spaarnwoude (Stompetoren) is located on the shoreline most inland. The city of Haarlem is the next (younger) beach ridge, and the subsequent the village of Santpoort. On many beach ridges remains of prehistoric habitation was found during excavations. This was due to higher ground a good place to live, protected from the sea.
