Vysoká Hill.


Vysoká is a hill near Havlíčkův Brod in Czechia. Crystals of a number of metals can be found in the fields, it is a polymetallic deposit. In ancient times, hot igneous rock penetrated into the subsoil at a depth of several hundred meters, which “boiled” the rocks above it. The metals in the overburden crack brought hot solutions under high pressure. As the temperature dropped, the metals crystallized, and erosion carried away some of the upper layers, bringing the veins closer to the surface.

We measured this interesting radargram, which probably showed the interface of two rocks or some deep crack.

And we can also make a detail of the purple area at a depth of about 200 m.
