The main aim of this paper is the environmental comparison of the early AMH sites, as recorded in loess deposits within Moravian valleys, Czech Republic. Three main Gravettian localities within the Moravian corridor with sedimentological records of the last 30 000 years were studied. The well known and long-studied site of Dolní Věstonice in south Moravia, the site of Předmostí situated close to the Moravia/Silesia border, which has yielded the largest mammoth bones accumulations in Central Europe, and the locality of Hošťálkovice in the southern edge of Silesia in the north east Czech Republic. Each of these sites displays a distinctive sedimentological and climatic record. The data based mainly on the sedimentological, micromorphological and geochemical record show that during Gravetian period Dolní Věstonice had the most stable environment with good conditions for preserve short climate changes. Although the environment was quite stable, there were seasonal washouts and seasonal thawing and freezing cycles. Permafrost developed within the LGM above the cultural layer. The Předmostí site recorded a quite unstable environment including regular washout movements and landslides. Such an environment depended mainly on the increased precipitation within this area. The LGM is also recorded by the signs of permafrost, in this case displayed as frost edges. Hošťálkovice is the least well preserved locality, lacking a well developed cultural layer and paleopedological record. Dry permafrost is recorded here. In general, palaeolithic hunters had to adapt, not only to seasonal changes of environmental conditions, but also changes across the landscape during their migrations within Moravian corridor. Probably the presence of permafrost connected with the humidity was the reason for the slow shift of those cultures toward the North European Glaciation and LGM.
