Tisá Rocks

About a kilometre west of them on the outskirts of Tisá stands the coarse- and medium-grained muscovite-biotite-orthogneiss of the Eastern Ore Mountain region.

Horizontal weathering is found in the upper layers and have created several bizarre shapes, such as the rock called the Steinpilz ("boletus edulis" - a type of edible mushroom) which is easily accessible.

The nearby area surrounding the Tisá Rocks to the north and south is covered by diluvial sediments of loam, sand and boulder-containing scree.

In the sandstone are heavy concentrations of ferrous minerals on closely spaced strata, that can be identified from their yellow to red stripes of colour and predominantly horizontal.

A striking feature in many places where the lower strata are visible are small and large cavities as well as occasional tunnels with an oval cross-section, whose walls are often covered with calcareous sinter deposits.
