Based on field observations conducted in the Pravaya Khetta River basin, an analysis of the so-called domed-hummocky peatbog formations occurring in the northern taiga of Western Siberia is presented. The morphological, lithological and thermal characteristics of these peatbogs are described alongside their development and degradation processes. The results confirm that hummocks are relict forms fashioned in the Late Holocene during a climatic cooling phase following the thermal maximum. Their formation was driven by water migration and frost heaving, while current conditions indicate progressive degradation primarily caused by thawing of the frozen core.
