West of Varna (Bulgaria), in the only desert in the country, a rare natural phenomenon can be seen, called Pobiti Kamani (planted stones).
Hundreds of stone columns 5 to 7 m high (some to 10 m high) and a thickness of 30 cm to 3 m, with very different cross-sections, extend over an area of several square kilometers.
There are various hypotheses about the origin of the formations that formed under the sea floor 50 million years ago in the Lower Eocene. On the one hand, an organic origin is assumed and the formation is attributed to deposits of corals and algae. On the other hand, a mineral origin is assumed, whereby the weathering has formed prismatic rock formations. The formation of sand-lime deposits is also assumed to be the cause.
These formations were exposed by erosion and tectonic uplift.

With SV you can explore this "stone forest".
