Core drilling

In order to gain knowledge of the 187 hectares of reclaimed land, drilling samples were taken in collaboration with a Dutch engineering company.

 

During the first part of the preliminary investigation, from May to August 2012, Museum Lolland-Falster collaborated with a team of specialists from the Dutch engineering company Sialtech to drill up 987 thin, 70 mm cores from the Lolland underground.

 

Searching for traces of human and natural activities

The cores showed clearly which soil types could be found at different depths and when landscape changes had taken place in the area. 378 of the drilling samples from the 187 hectares of reclaimed land were subsequently examined closely with particular attention to how the different soil layers were positioned in relation to each other. The other drilling cores were examined for antiquities and thus for traces of human activity. All drillings were carefully measured by means of GPS and a total station, making it possible to place them in relation to each other and thus gain a visual overview of the Stone Age appearance of the coastal area.

Localisation of settlements

Based on the many drilling samples, the museum prepared a landscape model of what the coast would roughly have looked like 4,000 years BC. The model clearly showed the distribution of land and water, and when used in combination with existing knowledge about Stone Age settlement patterns, it was possible to predict where local Stone Age settlements could be found.
