The natural monument covers 3 hectares. The bizarre two- to three-meter-high sandstone cliffs made of hardened glass sand provide an ideal picnic spot. They are reminiscent of the rock formations in Saxon Switzerland. The fine quartz sand has been mined in the area since the 19th century and used to produce colorless glass.

In the south of the Lusatian lignite mining area, very pure quartz sands are found beneath the Second Lusatian Seam, which were deposited there about 16 million years ago (Lower Miocene) as dune, beach or delta sands.[3] Since the first mining contract in 1857, the Hohenbocka glass sands, which are particularly poor in iron(III) oxide, became known worldwide in the following decades for the production of colorless and optical glasses.[3] Between Hohenbocka and Guteborn, silicification of the glass sands occurred in numerous narrowly defined places, which today form the striking rock formation of Buck's Switzerland at the former Heinrichsschacht sand pit.

If you want to get from the sandstone cliffs to the observation tower, you have to push your bike up a few stairs

In many places you walk in the forest in the quartz sand as if you were on a Baltic Sea island. The company premises that are cordoned off from mining alternate with a forest and lake landscape that has already been quite well renatured.
