High-Himalayan glaciers thinning
This fascinating image shows a variety of textures formed in ice of the Khumbu glacier in Nepal; one of the main glaciers that drain the Everest area and a stop on the most common route to the summit.
I’m sharing this image to illustrate some new scientific work on glaciers like this one in the highest parts of the Himalaya. Ponder this question to go with this photo; how do you determine whether a glacier at this altitude is shrinking or growing?
