Limburg (Weilheim an der Teck)

The Limburg is a mountain of volcanic origin, more precisely a formerly active volcanic vent of the Swabian Jura. However, it does not correspond, despite its striking cone shape the Ashes volcanoes on the type of Etna or Vesuvius. Before about 17 million years ago there came here to massive gas and dust explosions when percolating water met in the columns of the Jura on a magma bubble that had formed in the depths. The up broken rocks fell back into the crater and solidified over time to basaltic. Here no molten lava came to the surface. She remained rather stuck in the volcanic vent and froze there to Basalt. In the following year, millions the Jurassic layers were eroded more and more. The Basalttuffpfropf was more resistant than the surrounding limestone and remained as the northern slope of the Swabian Alb mountain upstream cone stand and testified that this formerly extended further to the north.
