High altitude karstic environments often preserve permanent ice deposits within caves, representing a lesser-known portion of the cryosphere. Despite being not so widespread and easily reachable as mountain glaciers and ice caps, ice-caves preserve a great deal of information about past environmental changes and paleoclimatic evolution. Since one of their main characteristics is to have ground-ice ...[Read More]

At the transition from the Gobi Altay ranges to the Valley of the Lakes in South West Mongolia, the Ikh Bogd mountain towers almost 3000 m above the aridifying endorheic Orog Nuur Basin.

Simultaneously, strong south-eastward winds create beautiful barchan ...[Read More]
