Geology

Short characteristics of the site: Blocky and debris flows in the brook valley. The rounded blocks consist of dark biotite-amphibole tonalite. The flows represent processes of frost weathering, and clastic materials have been transported into valley as debris tongues. Fine grained clasts were later removed and so nowadays debris flows consists only of pebbles and blocks. The locality belongs to Quaternary of the Brunovistulicum Zone.
