Study of these features is relevant for the palaeoenvironmental reconstruction of maritime Antarctica because they are indicators of permafrost and periglacial conditions.
Some rock glaciers in the Dry Valleys might be ancient features that provide information on past glacial advances. Instituto Ant⁄rtico Argentino and Centro Austral de Investigaciones Cient™ficas, … Rock glaciers are found in the peripheral regions of Antarctica particularly in the Antarctic Peninsula region.

[1] We present radar interferograms of rock glaciers in the Beacon Valley sector of the McMurdo Dry Valleys, in East Antarctica, as part of a comprehensive study of surface processes in the area.

Rock glacier, tonguelike body of coarse rock fragments, found in high mountains above the timberline, that moves slowly down a valley.The rock material usually has fallen from the valley walls and may contain large boulders: it resembles the material left at the terminus of a true glacier.Interstitial ice usually occurs in the centre of rock glaciers. [1] We present radar interferograms of rock glaciers in the Beacon Valley sector of the McMurdo Dry Valleys, in East Antarctica, as part of a comprehensive study of surface processes in the area. By continuing to browse this site you agree to us using cookies as described in … Rock glaciers, which are common not only to the Dry Valleys but throughout the Antarctic, are important archives of glaciological and climatological data, as well as important landforms to monitor with future potential warming. They affect us through their connections with the ocean and sea level, and environmental change is having rapid consequences in Antarctica. To the right of the lobate rock glacier, a few much smaller rock glaciers have formed at the base of a talus slope. Due to the relative absence of net precipitation (snow) in this region and the stability of the surface, the rock glaciers maintain excellent coherence of the radar returns over several years.

Study of these features is relevant for the palaeoenvironmental reconstruction of maritime Antarctica because they are indicators of permafrost and periglacial conditions. In Antarctica, rock glaciers have only been surveyed on the Antarctic Peninsula, Ellsworth Mountains and in Victoria Land. The ages of the rock glaciers studied in Antarctica to date are very variable. Rock glaciers are found in the peripheral regions of Antarctica particularly in the Antarctic Peninsula region. Recent acceleration of rock glaciers is well recognized in the European Alps, but similar behavior is hardly documented elsewhere. In central Taylor and Pearse valleys rock glaciers cover at least 10% of the valley walls and occur at … Rock glaciers and buried ice are common in the McMurdo Dry Valleys, Antarctica.
