Geology

Short characteristics of the site: Quaternary, areas of continental glaciation. "Garden" with collection of erratic boulders. This collection exposes 72 erratic boulders, mostly of porphyric coarse grained granite of a Fenniscandinavian provenance. Also some other types of rocks are present, such as pegmatites, orthogneisses, metaquartzites and also sandstones. They were studied in detail petrologically, results published and described briefly on information table. Very valuable collection of erratic boulders. The locality is situated in a future Geopark Jeseníky.
