Very nice area, in winter as in summer

The Pfrunger-Burgweiler Ried (formerly Pfrunger Ried) is, after the Federsee, the second largest contiguous moorland in southwest Germany with 2600 hectares. Origin
Edit
The current moorland is the remnant of a post-glacial lake that gradually filled with sediment and mineral deposits after the Rhine glacier melted and thus partially silted up. This is how fens were created and, in some places, raised bogs above them. These areas were characterized by depth and wetness and were not suitable for permanent human settlement. However, mineral infiltration also created solid islands on which the first permanent human settlements were built. The core area of the area remained uninhabited and was considered uncultivable, inferior land.
