Take some ice, mix in some rock, snow and maybe a little mud and the result is a rock glacier. Unlike ice glaciers (the ones we are most familiar with), rock glaciers have very little ice at the surface. Looking at today’s featured image, you’d be forgiven for thinking the Morenas Coloradas rock glacier wasn’t a glacier at all. But appearances can be misleading; as Jan Blöthe (a researcher at the ...[Read More]

This month’s GeoRoundUp is a slight deviation from the norm. Instead of drawing inspiration from popular stories on our social media channels and unique or quirky research featured in the news, we’ve rounded up some of the stories which came out of researcher presented at our General Assembly (which took place last week in Vienna). The traditional format for the column will return in May! Major st ...[Read More]

Nestled among the high peaks of the Karakoram, in a difficult to reach region of China, lies Kyagar Glacier. It’s trident-like shape climbs from 4800 to 7000 meters above sea level and is made up of three upper glacier tributaries which converge to form an 8 km long glacier tongue. Until recently, it’s remoteness meant that studying its behaviour relied heavily on the acquisition of data by satel ...[Read More]

Drawing inspiration from popular stories on our social media channels, as well as unique and quirky research news, this monthly column aims to bring you the best of the Earth and planetary sciences from around the web. Major story While the March headlines might not have been dominated by a particular story, the state of the Earth’s climate has definitely been the overarching theme of the month. ...[Read More]
