Catastrophic Slope Processes in Glaciated Zones of Mountainous Regions
Catastrophic slope failures that occur in glaciated zones of mountain ranges at high altitudes can be considered as landslides in cold regions, since ice plays an important role in their origination and emplacement. Case studies of the XX Century rock avalanche that fell onto the glacier and of the extraordinary prehistoric ice-rock avalanche are described briefly. They demonstrate that presence of large quantities of ice in the glaciated zones of high mountains results in significant masking of the origin of debris accumulations that could be found either on glaciers or at the feet of heavily glaciated slopes.

My study in the Alay valley was performed within the frames of the UNU PALM Project “Sustainable Land Management in the High Pamir and Pamir-Alai Mountains in Central Asia”. During the 2009 field trip in this region I worked together with Mr. Alexander Meleshko, who passed away prematurely in 2010.
