Groundwater discharge sustains the baseflow of alpine headwater streams, which is critical for water supply and aquatic environments in mountainous regions. Periglacial landforms typical headwaters (e.g., talus, moraine, rock glacier, meadows) are important aquifers watersheds. This study examines hydrological function an aquifer complex a small basin Canadian Rockies. The consisting meadow und...

Iceland’s glaciers are particularly sensitive to climate change, and their margins respond to trends in air temperature. Most Icelandic glaciers have been in retreat since c. 1990, and almost all since 1995. Using ice-front measurements, photographic and geomorphological evidence, we examined the record of ice-front fluctuations of Virkisjökull–Falljökull, a steep high-mass-turnover outlet glac...

Moraine sequences of mountain glaciers can be used to infer spatial and temporal patterns of climate change across the globe. Alaska is an accessible high-latitude location in the Northern Hemisphere and contains a rich record of alpine glaciation. Here, we highlight the key chronologies from three mountain ranges in Alaska that reveal the timing and spatial extent of Late Pleistocene glaciatio...

Analysis of new chronological data, including 55 radiocarbon, 1 OSL, and 8 dendrochronological dates, obtained in the upper reaches trough valleys within Katun, North Chuya, South Chikhachev ranges, together with previously published ones, specifies climatically driven glacier dynamic Russian Altai. Available data refute traditional concept Altai Holocene glaciations as a consecutive retreat La...
