【 摘 要 】

Google Earth satellite images analysis corroborated with materials of geological, geomorphological and landscape survey shows in Zavolzhye-Urals region wide distribution of relic relief forms that are shaped under Pleistocene periglacial conditions. Such forms are not always visible in field, but can be well read in satellite images. Following of them are well developed: continental dunes, relic thermokarst lakes, and the microform complexes determined by permafrost influence on the geological substratum: polygonal and hillock-pit complexes, nival relief complex including amphitheatres, niches, trays, etc.
