Tors represent one of the most characteristic landforms in the uplands and mountains of Central Europe, including the Sudetes, Czech-Moravian Highlands, Šumava/Bayerischer Wald, Fichtel- gebirge or Harz. These features occur in a range of lithologies, although granites and gneisses are particularly prone to tor formation. Various models of tor formation and development have been pre- sented, and for each model the tors were thought to have evolved under specific environmental con- ditions. The two most common theories emphasised their progressive emergence from pre-Quaternary weathering mantles in a two-stage scenario, and their development across slopes under periglacial conditions in a one-stage scenario. More recently, tors have been analysed in relation to ice sheet ex- tent, the selectivity of glacial erosion, and the preservation of landforms under ice. In this paper we describe tor distribution across Central Europe along with hypotheses relating to their formation and Key words: development, arguing that specific evolutionary histories are not supported by unequivocal evidence tors, and that the scenarios presented were invariably model-driven. Several examples from the Sudetes deep weathering, are presented to demonstrate that tor morphology is strongly controlled by lithology and structure. periglacial processes, The juxtaposition of tors of different types is not necessarily evidence that they differ in their mode glacial erosion, of origin or age.
