The post, by Irene Marzolff, a researcher at Johann Wolfgang Goethe-Universitaet, explores how the mountains, rivers and soils of the High Atlas in Morocco are intrinsically linked to the agriculture of the region. The image was taken in the southern slopes of the Western High Atlas, north of the city of Taroudann ...[Read More]

Antelope Canyon, located in Arizona, USA, was formed by erosion of the Navajo Sandstone, primarily due to flash flooding and secondarily due to other sub-aerial processes (think of physical weathering processes such as freeze-thaw weathering exfoliation and salt crystallisation). Rainwater runs into the extensive basin above the slot canyon sections, picking up speed and sand as it rushes into the ...[Read More]

Layer upon layer of sand, clay and silt, cemented together over time to form the sedimentary units of the Badlands National Park in South Dakota, USA. The sediments, delivered by rivers and streams that criss-crossed the landscape, accumulated over a period of millions of years, ranging from the late Cretaceous Period (67 to 75 million years ago) throughout to the Oligocene Epoch (26 to 34 million ...[Read More]

On the 25th April 2015, Viktor Bruckman, a researcher at the Austrian Academy of Sciences, and a team of his colleagues were a few hours into a hike between the settlements of Lamabagar, in a remote area of northeastern Nepal, and the Lapchi Monastery when a magnitude 7.8 earthquake struck Nepal. Their journey cut short by the trembling Earth, stranded in the heights of the Himalayas, this is thei ...[Read More]
