The paper deals with the influence of snow conditions on periglacial landforms. The research was carried out on four study sites in the summit parts of the Krkonoše Mountains with occurrence of recently active periglacial landforms (solifluction lobes, ploughing blocks, peat hummocks and sorted circles). Depth and duration of snow cover were measured there two years. Regularities in snow distribution were evaluated and compared with the position of selected periglacial landforms. The results prove that there is a close relationship between the low snow cover and occurrence of sorted circles and that the distribution of peat hummocks has not any connection with snow cover. Relationships between solifluction lobes and ploughing blocks and snow were rather ambiguous.
