Geosciences Column: The science behind snow farming

Geosciences Column: The science behind snow farming

For roughly the last decade, some ski resorts and other winter sport facilities have been using a pretty unusual method to ensure white slopes in winter. It’s called snow farming. The practice involves collecting natural or artificially made snow towards the end of winter, then storing the frozen mass in bulk over the summer under a thick layer of sawdust, woodchips, mulch, or other insulating mat ...[Read More]

Imaggeo on Mondays: Tongue of a small giant

In a world where climate change causes many mountain glaciers to shrink away, bucking the ‘melting’ trend is not easy. In today’s post, Antonello Provenzale, a researcher in Italy, tells us of one glacier in the Alps which is doing just that. Mountain glaciers are retreating worldwide, with the possible exception of the Karakoram area. For most glaciers, ablation (ice melt) durin ...[Read More]

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]

Imaggeo on Mondays: Why does a Norwegian glacier look blue?

This picture shows the outlet glacier Engabreen running down from the plateau of Svartisen in Norway. Svartisen ice cap comprises two glacier systems of which the Vestre (western) Svartisen is Norway’s second largest glacier. Located right at the polar circle, Svartisen covers a total of 369 km² of the Nordland region. These coastal mountains accumulate a snowpack of 5-7 m depth through the winter ...[Read More]
