Abstract
Periglacial landforms above alpine timberline in the High Sudetes are unique because they are the best preserved in these areas due to the specific climatic conditions in the mountains. Some of periglacial landforms (earth and peat hummocks, sorted circles, some non-sorted stripes, small nivation hollows, solifluction lobes and ploughing blocks) are active, which is reflected in morphology or internal structure changes, and they represent equivalents of landforms occurring in Scandinavia or in the incomparably higher Alps.
Many types of periglacial landforms in the High Sudetes are endangered critically, so they need heightened protection, including public education, so that tourists do not destroy these unique and vulnerable landforms.
