Uhlířský vrch Nature Reserve 1

Basic information

Uhlířský vrch is an extinct volcano (671,7 m n. m.) at the south-western outskirts of Bruntál. Tufa quarries were established under this mountain peak in the second half of the 19th century. They turned into an extensive outcrop later on. The nature reserve including the outcrop´s vicinity was declared there in 1966 and nowadays it extends in the area of 3.70 ha.

Subject of protection

Extensive outcrop of an extinct volcano and the remains of tufa quarries from the second half of the 19th century are the subjects of protection.

Geology

One of the youngest extinct volcanoes in the Czech lands can be found in this site. Uhlířský vrch represents the remains of a stratovolcano smoothed to a large extent by denundation processes. According to research findings, there were at least two phases of explosive and effusive volcano activities. The surface parts of the terrain reveal the products of the younger phase. Basaltic rocks in the parietal area of the peak most likely come from lava and partially fissure – vein in the mid or lower part of the crater which was surrounded by annular ridge of volcanoclastics. 30 m high quarry walls enable to study the composition of volcanoclastic rocks – tufas in almost perfect state. The volcano activity dates back to the Lower Pleistocene. According to radiometric measurements the basaltic rocks were estimated to be about 1.9 million years old.
