Striking basalt formation
If you walk from the Wasserkuppe to the Pferdskopf, you will pass the Lerchenküppel. This striking basalt formation rises on the south-western slope of the Wasserkuppe.
Two benches invite you to linger. On an information board geologically interested people will find interesting facts about the formation of the Lerchenküppel.
Here you are in the root area of a volcano. If you take a closer look at the cliff, you will recognize the platy cleft arrangement. This indicates that the basalt melt was already outgassed and cooled down and therefore must have taken place late.
This is the plug that was stuck in the volcano root.
Lerchenküppel is Hessian Geotope of the Year 2014
The Hessian State Office for Environment and Geology had awarded the rock, also known as “Lerchenkopf”, the title of “Hessian Geotope of the Year” in 2014.
The Lerchenküppel (also known as “Karfreitagsstein” or “Steinküppel”) is a small rock, about 4 m high and at the base about 10 m wide. It consists of a primitive basanite from the volcanic post-phase of the Middle Miocene, dated by Lippolt (1982) according to the K/Ar method to 14 million years. In contrast to the flying monument, however, the olivine nodules are missing here. In the outer appearance the absence of the columnar development is noticeable. Instead, an onion-skin shaped, platy secretion can be seen on the west side. This is mainly found in relatively tough melts. (Source: Hessian State Office for Environment and Geology)
