Journal of Quaternary Science, EarlyView.ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Processes acting to produce glacial detritus [PDF]
, 1969 The traditional view of attrition and abrasion as the major agents producing glacial debris is considered in the light of recent work by engineering geologists and geomorphologists.

A talus rock glacier in Nantlle Valley, North Wales
Journal of Quaternary Science, EarlyView.ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...

Glacial Geomorphology of southern Alberta, Canada [PDF]
, 2009 During deglaciation from the Last Glacial Maximum three terrestrial ice streams within the south western sector of the Laurentide Ice Sheet competed and coalesced in southern Alberta; the High Plains Ice Stream (HPIS), Central Alberta Ice Stream (CAIS ...

Late Quaternary geomorphological processes and landscape evolution in the Khur Basin, central Iran [PDF]
Eiszeitalter und GegenwartThe interior of the Central Iranian Plateau is an important area for the study of the palaeoenvironmental controls of early human dispersal in arid regions.

Journal of Quaternary Science, EarlyView.ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.

Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska
Permafrost and Periglacial Processes, EarlyView.ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

Disposition Model for Permafrost Degradation in Mountainous Regions
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Permafrost is a widespread thermal phenomenon in Arctic and high mountain regions that, in combination with steep terrain, exerts a key control on slope stability. Its degradation in response to climatic warming can modify the likelihood and timing of rockfall, debris flow and related mass movements. Robust information on the current state and

The American geomorphology before W. M. Davis, with special regard to J. W. Powell and G. K. Gilbert
Acta Geographica Slovenica, 2001 The beginnings of the North American geomorphology are closely connected with the development of its geology. Many of the most renowned American geologists of the time (up to the end of 19th century) got their real reputation in many cases due to the ...

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.
