The unique record of Za Hájovnou Cave.
The cave Za Hájovnou is a former sinkhole. It was active from the Early Pleistocene until the beginning of the Cromerian Interglacials complex. This publication assesses the sediments of the two main corridors, the Vykopaná chodba and the Narozeninová chodba. Only two exposures have been found with sediments from the Last Interglacial (Eemian) and from the Last Glacial. The sediments come mostly from the Middle Pleistocene. The layer sequences of the two corridors are different. It is possible to classify all the Middle Pleistocene sediments into two distinct groups. Both groups were formed in a warm interglacial climate and differ in conservation of the osteological material due to the different sedimentary content. In the Narozeninová chodba, these groups are separated by a large talus cone. The most important question is if there were one or more interglacials in the Middle Pleistocene here. Both alternatives are discussed in this paper.
