Deglaciation of Fennoscandia
To provide a new reconstruction of the deglaciation of the Fennoscandian Ice Sheet, in the form of calendar-year time-slices, which are particularly useful for ice sheet modelling, we have compiled and synthesized published geomorphological data for eskers, ice-marginal formations, lineations, marginal meltwater channels, striae, ice-dammed lakes, and geochronological data from radiocarbon, varve, optically-stimulated luminescence, and cosmogenic…
Glacial geomorphology of the Altai and Western Sayan Mountains, Central Asia
In this article, we present a map of the glacial geomorphology of the Altai andWestern Sayan Mountains, covering an area of almost 600,000 km2. Although numerous studies provide evidence for restricted Pleistocene glaciations in this area, others have hypothesized the past existence of an extensive ice sheet. To provide a framework for accurate glacial reconstructions of the Altai and Western Sayan Mountains, we present a map at a scale of 1:1,00…
Cosmogenic nuclide exposure ages for moraines in the Lago San Martin Valley, Argentina
At several times during the Quaternary, a major eastward-flowing outlet glacier of the former Patagonian Ice Sheet occupied the Lago San Martin Valley in Argentina (49°S, 72°W). We present a glacial chronology for the valley based on geomorphological mapping and cosmogenic nuclide ( 10 Be) exposure ages ( n = 10) of boulders on moraines and lake shorelines. There are five prominent moraine belts in the Lago San Martin Valley, associated with exte…
Glacial Lake Vitim, a 3000-km 3 outburst flood from Siberia to the Arctic Ocean
A prominent lake formed when glaciers descending from the Kodar Range blocked the River Vitim in central Transbaikalia, Siberia. Glacial Lake Vitim, evidenced by palaeoshorelines and deltas, covered 23,500 km 2 and held a volume of ~ 3000 km 3 . We infer that a large canyon in the area of the postulated ice dam served as a spillway during an outburst flood that drained through the rivers Vitim and Lena into the Arctic Ocean. The inferred outburst…
Glacial meltwater landforms of central British Columbia
Please click here to download the map associated with this article. The Cordilleran Ice Sheet (CIS), which grew and melted repeatedly across the mountain ranges of westernmost Canada during the late Cenozoic, has imprinted its legacy in the form of glacial landforms, such as meltwater landforms. However, despite their abundance, a coherent effort to map meltwater landforms has been lacking. Here, we present a first regional geomorphological map o…
Glacial geomorphology and glacial lakes of central Transbaikalia, Siberia, Russia
A glacial geomorphological map is presented covering the poorly investigated mountainous region of central Transbaikalia, Russia.Interpretation of geomorphology is achieved using remotely sensed data (SRTM digital elevation model, Landsat 7 ETM+ satellite imagery and Google Maps).Glacially modified terrain is mapped together with moraines, glacial lineations and meltwater channels, in order to provide an estimate of the area affected by glaciatio…
The Glacial Map of southern South America
Please click here to download the map associated with this article. This paper describes The Glacial Map of southern South America. This is a new map of the glacial geomorphology of southern South America between latitudes 38°S and 56°S, approximately the area covered by the former Patagonian Ice Sheets. The map was compiled from interpretation of remotely sensed images (Landsat 7 ETM+, pan-sharpened Landsat 7 and ASTER scenes). The mapped geomor…
Glaciar León, Chilean Patagonia
Glaciar León is a temperate, grounded outlet of the eastern North Patagonian Icefield (NPI). It terminates at an active calving margin in Lago Leones, a 10 km long proglacial lake. We take a multidisciplinary approach to its description and use ASTER imagery and clast sedimentology to describe the geomorphology of the glacier and its associated moraines. We date periods of glacier retreat over the last 2500 years using a combination of lichenomet…
A glacial lake outburst flood associated with recent mountain glacier retreat, Patagonian Andes
Geomorphological mapping, sedimentology, lichenometry and dendrochronology were used to assess the nature and timing of glacier recession, moraine development and catastrophic mass movements in a tributary of the Leones valley, east of the Hielo Patagónico Norte, Chile. We show that during the 'Little Ice Age' Glaciar Calafate advanced downvalley to produce a terminal moraine. Recession of the glacier from this position occurred in the 1 870s and…
Fast-flowing outlet glaciers of the Last Glacial Maximum Patagonian Icefield
Glacial geomorphology around the Northern Patagonian Icefield indicates that a number of fast-flowing outlet glaciers (the continuation of ice streams further upglacier) drained the icefield during the Last Glacial Maximum. These topographically controlled fast-flowing glaciers may have dictated the overall pattern of Last Glacial Maximum ice discharge, lowered the ice-surface profile, and forced the ice-divide westward. The influence of the fast…
Map of the glacial geomorphology of north-central Québec-Labrador, Canada
Please click here to download the map associated with this article. The “map of the glacial geomorphology of North-Central Québec-Labrador, Canada”, based on aerial photograph interpretation, presents the distribution of glacial and glaciofluvial landforms, such as glacial lineations, eskers, ribbed moraine, and glacial lake shorelines. It covers an area of approximately 180,000 km2 between 53° and 56° 30′ N and 64° and 74° E and shows that north…
Observations on weathering forms at the Caniapiscau Reservoir, North‐Central Québec, Canada
Weathering forms were encountered during field work in a formerly glaciated shield area in Canada that lies within the Labrador‐Ungava sector of the former Laurentide Ice Sheet. The granite and gneissic granite in the study area display features of surface weathering, such as weathering pits, and of deep weathering, such as an exposed weathering front with associated gravelly saprolite and core stones. Most observations were made along the shorel…
