A late Pleistocene glacial maximum during MIS 3 in the Chersky Mountains, central northeast Siberia
The glacial history of northeast Siberia is poorly understood compared with other high-latitude regions. Using 10 Be and 26 Al exposure dating together with remote sensing, we have investigated the glacial history of a remote, formerly glaciated valley in the Tas-Kystabyt Range of the Chersky Mountains in central northeast Siberia. Based on measurements from moraine boulders and bedrock samples, we find evidence for deglaciation of the valley 45.…
Glacial geomorphology of the northwest Laurentide Ice Sheet on the northern Interior Plains and western Canadian Shield, Canada
The majority of the Northwest Territories of mainland Canada was covered by the Laurentide Ice Sheet during the Last Glacial Maximum. The increasing coverage of high resolution remotely sensed data provides new opportunities to map the glacial geomorphology and study the glacial history of this remote location. Here we present a comprehensive map of glacial landforms within the northern Interior Plains and adjacent areas of the Canadian Shield, c…
The glacial geomorphology of the Mackenzie Mountains region, Canada
During the Last Glacial Maximum, the Mackenzie Mountains region was glaciated by three distinct ice sources; the Laurentide Ice Sheet, the Cordilleran Ice Sheet, and independent montane glaciers. Rapid ice sheet thinning of the Laurentide-Cordilleran ice saddle in the south of this region contributed to rapid sea level rise events and influenced the style of deglaciation to the north. The current understanding of the glacial history of the broade…
Using 10 Be dating to determine when the Cordilleran Ice Sheet stopped flowing over the Canadian Rocky Mountains
During the last glacial maximum the Cordilleran and Laurentide ice sheets coalesced east of the Rocky Mountains and geomorphological evidence indicates ice flowed over the main ridge of the Rocky Mountains between ~54–56°N. However, this ice flow has thus far remained unconstrained in time. Here we use in situ produced cosmogenic 10 Be dating to determine when Cordilleran ice stopped flowing over the mountain range. We dated eight samples from tw…
Glacial geomorphology of the central sector of the Cordilleran Ice Sheet, Northern British Columbia, Canada
Northern British Columbia was repeatedly covered by the Cordilleran Ice Sheet (CIS) during the glacial periods. However, its mountainous terrain and remote location have thus far impeded our understanding of the central sector of the ice sheet. The improved resolution of remotely sensed data provides new opportunities to unravel the glacial history of this inaccessible location. Here, we present a comprehensive map of glacial landforms for the ce…
Beryllium-10 dating of the Foothills Erratics Train in Alberta, Canada, indicates detachment of the Laurentide Ice Sheet from the Rocky Mountains at ~15 ka
The Foothills Erratics Train consists of large quartzite blocks of Rocky Mountains origin deposited on the eastern slopes of the Rocky Mountain Foothills in Alberta between ~53.5°N and 49°N. The blocks were deposited in their present locations when the western margin of the Laurentide Ice Sheet (LIS) detached from the local ice masses of the Rocky Mountains, which initiated the opening of the southern end of the ice-free corridor between the Cord…
Glacial geomorphology of the Šumava / Bayerischer Wald mountains, Central Europe
During Quaternary glacial periods, the Šumava / Bayerischer Wald mountains were subject to mountain glaciations. Recent studies have focussed mainly on the several well-developed cirques. However, the glacial geomorphology of the mountain range as a whole has not yet been mapped from digital data. Here we use high-resolution digital elevation models to identify over 300 erosional and 40 depositional landforms of glacial origin. Our study provides…
Glacial landforms of northwest Saskatchewan
A comprehensive map of glacial landforms is presented for the area of northwest Saskatchewan, Canada. Remote sensing of 1-arc (∼30 m resolution) Shuttle Radar Topography Mission digital elevation models over an area of approximately 15,000 km2 were used as the primary data source for landform identification. A total of 16,856 landforms were identified pertaining to Quaternary glacial and postglacial activity. Ten landform types were mapped: ice f…
Ice streams in the Laurentide Ice Sheet
Rapidly flowing ice streams dominate the drainage of continental ice sheets and are a key component of their mass balance. Due to their potential impact on sea level, their activity in the Antarctic and Greenland Ice Sheets has undergone detailed scrutiny in recent decades. However, these observations only cover a fraction of their 'life-span' and the subglacial processes that facilitate their rapid flow are very difficult to observe. To circumve…
Pleistocene Glacial Lake Vitim outburst flood, central Transbaikalia, Siberia
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…
