Children of the Sea – the Allgäu and Lechtal Alps

Sand, mud, shells from  dead animals, dead plants – this t is what the mountains of the Allgäu and Lechtal Alps were created from.

Approximately 240 million years ago the current  continents formed the supercontinent of Pangaea.  The Thetys Ocean was one of the seas surrounding Pangaea and that  is where our mountains were formed. Over millions of years the lime shells from  dead sea animals, sand, dead parts of plants and mud sank to the bottom  of the sea there. From the initially lose layers of sediments, sediment rocks formed from  the enormous pressure.

Today the process that created the Alps is still ongoing – a pushing, raising and folding of the former sea floor.

Ice is responsible for what the Lechtal looks today. During the Würm glacial stage (110,000 – 10,000 B.C.) the majestic Lech Glacier, the ice masses of which reach into the foothills of the Alps, was created. 800m of thick ice lay in the valley basin of Reutte, only the highest summits could be seen. With its ice masses, the Lechtal Glacier blocked the side valleys. Which is the reason why the side-valleys of the Lechtal are suspended valleys – they are several hundred metres above the main valley. Impressive gorges and waterfalls at the exit of these side-valleys still show signs of their origin.
