Description :
The Turgen Mountains lie in northwestern Mongolia, roughly 80 km south of the Russian border. Analyses of field data, repeated photographs from 1910 and 2010, topographic maps from 1970, and satellite imagery from 1992 and 2010 were used to describe the changes in the glacial system. The results suggest that while the snow and ice volume on the summits appears to be intact, lower elevation glaciers show significant recession and ablation. From 1910 to 2010, West Turgen Glacier receded by c. 600 m and down-wasted by c. 70 m. This study successively demonstrates the utility of using historic expedition documents to extend the modern record of glacial change.
