In Hüfingen, a “Geo-Column” offers insight into geological history.

Thanks to the lobbying efforts of the Environmental Bureau a “Geo column” was errected a few years ago in Hüfingen, funded by the Nature Park. A local stonecutter was commisioned by the city to build an obelisk with a surface providing insight into the Südbaar’s geological heritage.
Only few inhabitants of the Baar know that they live in one of Germany’s geologically most interesting parts. The southern German cuesta with its layers of granite and gneiss, red sandstone, muschelkalk, keuper and jura usually spans out over a distance of 100-300 km. However in the southern Südbaar, being a point of culmination, this sucession is compressed and observable over only 15 km.
Naturally, not every layer could be displayed; certain types of stone would not have survived the weather conditions.

But within every bigger rock formation there were more solid layers, which met the requirments. And so the lower part of the column is comprised of granit, red sandstone und muschelkalk. Keuper is represented by red sandstone, after it was identified as the most resilient layer. All three jurae include such layers as well.

It was not an easy task to find sources of every layer in the region. Local fossil experts were a great help. On one of the obelisk’s four sides – as long as it was possible – particularities of each layer, such as ammonites, plants and shells, were installed.

The obelisk can be found on the “Hüfinger Festplatz” next to the river Breg. Not only should it provide tourists with insight into the geological make-up of the surroundings but also remind the locals of how special their home is.
