Summary

[edit]
Description
Deutsch: Als Geotop und Naturdenkmal geschützte Karstquellen der Echaz. Die Quellen entspringen oberhalb des Dorfes Honau aus dem Hangschutt am Fuß des obersten Talabschnitts. Per Rückschreitender Erosion hat die Echaz das Tal tief in den Albtrauf eingeschnitten. Mehrere kleinere Quellen befinden sich weiter oben im steilen Talschluss, dem so genannten „Tobeltal“. Das Karstwasser entstammt dem Grenzbereich Impressamergel-Formation/Wohlgeschichtete Kalk-Formation (ox1/ox2). Das Einzugsgebiet der Quelle erstreckt sich über etwa 100 km² der südlich angrenzenden Albhochfäche. Die Schüttungen schwanken erheblich.
Durch sukzessive Ausfällung von gelöstem Kalk aus dem Wasser haben sich seit dem Arlantikum mehrere recht große Kalktuffterrassen gebildet. Auf der obersten Terrasse liegt Honau.

English: Protected Geotope and Natural monument karst springs of river “Echaz ” (tributary of the Neckar). The springs emerge above the village Honau. headward erosion of the river deeply cut into the escarpment (“Albtrauf”) of the Swabian Alb. Additional, but smaller, springs emerge from the “oxfordian” beds of the South German White Jurassic (ox1/ox2) in the upper, narrow part of the valley, called “Tobeltal”. The relatively large catchment area of the springs on the Alb’s plateau is more than 100 km2. The springs yield varies drastically, according to time of year and quantity of precipitation. Over thousands of years the upper section of the river formed several large terraces of “Kalktuff“ (very cavernous travertine).
