“I was told that there will be a piedmont glacier on the way from Station Nord, a Danish military base in northeast Greenland, to our destination in no-man’s-land next to the 79°N Glacier. On half the way, we passed the beautiful Elephant Foot Glacier, named after its symmetric shape originating from the viscous flow of the ice. The glacier is located on a peninsula and connected to a small ...[Read More]

The Zugspitze Geodynamic Observatory Germany (ZUGOG) has been setup on the summit of mountain Zugspitze at an altitude of almost 3000 m during 2018 with the main scientific objective being a better understanding of seasonal and long-term mass redistributions in the European Alps. This knowledge is very important (e.g. with regard to water storage and its high sensitivity to climate change), but is ...[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. The actively deforming mountain front shows traces of multiple earthquakes, which in turn affect the alluvial sediments deposited in the basin. Simultaneously, strong south-eastward winds create beautiful barchan ...[Read More]

The almost perfect rock pyramid in the foreground was formed by physical weathering and found in the Los Glaciares National Park in southern Argentina. The block was deposited on top of a rock surface polished by glacial erosion. The pyramidal peaks in the background are also the result of glacial erosion, albeit on a much larger scale.   Description by Christoph Mayr, after the description o ...[Read More]
