Sampling of water present in sinkhole formed in superficial salt-rich lacustrine deposits at Ghor Al-Haditha, Dead Sea eastern shore, Jordan, during a field campaign in October 2018. The water in this sinkhole flows into the Dead Sea in a surface stream channel formed in 2012. The water was highly acidic and extremely conductive, with a strong sulfurous odour. Understanding the chemistry of the wa ...[Read More]

Glen More, on the Isle of Mull, Scotland, is a classic locality for studying glacial landforms and sediments. Here, two prominent ice-transported boulders stand guard at the head of the valley, left behind after the Loch Lomond Readvance (Younger Dryas stade), the final pulse of Quaternary glaciation in Scotland. Behind them in the characteristic U-shaped valley, hummocky morraines are littered wi ...[Read More]

Driving eastwards through the San Luis Valley in south central Colorado, United States, the Great Sand Dunes emerge at the foot of the Sangre de Cristo Range in the northeast of the region’s upland plain. The origin story of these great dunes begins during a time of glacial melt, five to three million years ago, when the rivers of the surrounding mountains filled the basin with water and sediments ...[Read More]
