In the Khan–Hentei Nature Reserve, permafrost distribution is largely related to altitude. Periglacial processes and landforms are differentiated into four altitude‐based climatic zones. Their intensity varies with altitude, both upwards and downwards. Goletz (i.e. cryoplanation) terraces, frost hummocks, and solifluction are the main features. Frost cracking is reported from mires (bogs) in valley bottoms. The rate of frost weathering in the Orkon–Selengi mountain region was 0·0025 mm/a in 1977–78. © 1998 John Wiley & Sons, Ltd.
