요약 | Cryoplanation Terraces (CTs) are erosional landforms reminiscent of giant staircases, with alternating shallow sloping treads and steep scarps leading to extensive flat summits. CTs are associated with periglacial (cold and unglaciated) environments and are typically found in elevated positions on ridges and hillslopes. Despite identification and discussion in geomorphic literature as early as the 1890s in the Urals, and the early 1900s in Alaska and the Yukon Territory, a consensus still has not been reached on the processes involved in CT formation. Two hypotheses continue to receive support from different factions of periglacial geomorphologists: (1) CTs are controlled primarily by geologic structure |
