The Steinhirt , also Steinhirt-Klosterberg , is 578.4 m above sea level. NHN high central hill of the Steinheim basin , an impact crater in Baden-Württemberg . The Wäldlesfels stands on its summit .
Location and surroundings
This central hill in the Steinheim basin is located on the southern outskirts of Steinheim am Albuch . It has a diameter of between 800 and 900 meters and rises about 40 meters above its surrounding area. The hill is largely covered by agricultural land and only partially forested.
The Wäldlesfels at the summit of the Steinhirt is an approx. Eight meter high rock obelisk made of freshwater limestone . It is a popular climbing rock and offers bouldering opportunities up to level VIII . It is designated as a natural monument and protected geotope under the name of hot spring limestone cliffs on the Steinhirt, and some other limestone cliffs on the southern slope of the Steinhirt also have this status.
To the west of the Wäldlesfelsen lies the artificially created Lettenhülbe pond , which is also designated as a natural monument. The Hülbe was once an occurrence of the fever clover , but it no longer occurs here. Today it is important as a habitat for the mountain newt , otherwise the water is rather poor in species.
geology
The hill emerged as a central mountain about 14-15 million years ago due to the spring back of the ground after the meteorite impact that formed the Steinheim Basin.
The flanks of the central hill are formed by rocks from the Middle and Lower White Jurassic and are surrounded by a core of Brown Jurassic . This is particularly pronounced on the north side of the Steinhirts. The layers of the Brown Jura are inclined outwards, i.e. away from the middle of the hill, provided that they are on the sides of the Steinhirt-Klosterberg. The same applies to the layers of the White Jura, the so-called limestone and marl banks , which are also inclined outwards.
The Wäldlesfels represents only a remnant of the former ring of algae limestone rocks ( aragonite ) on the central hill. To this day, it is recognizable in its actual shape as a reef . The reef formed when the meteorite crater filled with water 14 million years ago and the central hill was completely covered. Lime-precipitating algae in the shallow water of the central hill covered by the lake gave rise to the reef. Various drill shell holes in the Wäldlesfels are evidence that it is a reef.
Dismantling
The original wreath of algae limestone rocks on the central hill was dismantled in the course of the 19th century, with a relief reversal by human hands. The gravel obtained was used for the construction of the Brenz Valley Railway . Actually, the Wäldlesfels should also have been removed if the Steinheimer Ludwig Schäffer had not successfully defended himself against the dismantling. Thus the rock remained as a last relic on the stone shepherd.
