Under the Hochjochferner glacier. Credit: Ilkka Matero.
What is happening under a glacier? This is a difficult questions to answer as accessing the glacier bed is usually not that easy. Here, we are getting a rare glimpse of the different processes and materials that are often found at the ice-bed interface. The photograph shows both sediments and hard rock, clear ice and dirty ice, and of course flowing water. No wonder these processes are complicated to say the least!
The photo was taken by Ilkka Matero (University of Leeds, U.K) during the excursion to Hochjochferner at the Karthaus summer school. See also the Image of the Week post from 18th of September to get an outside view of the side of the glacier.
