FORMER KETTLE HOLES – The farmland in Mecklenburg and West Pomerania is dotted with countless green holes, looking like small islands. These are points, where the farmland sunk and rain water gathered, forming small basins. The soil in these spots is too wet for farming, so they are circumvented by tractors. These small basins are the relics of the Ice Age and were formed by ice blocks embedded in the soft soil left over by retreating glaciers and debris transported by melt water. As they melted gradually, the ground sunk and melt water filled the cavities forming so called ‘dead ice holes’.
