People often say that GW is slow and hard to see. One place you can see it is in the mountains. I don’t have many pix that show it well, but here’s one pair. We’re looking at the Sulzenauferner. The first is from 2014, and is taken from the path up to the Beiljoch (which said col is visible in the lower pair of pix) between the Sulzenauhutte and the Dresdener. The Zuckerhutl is straight on, buried in cloud, how unusual.
And here’s the same thing back in 2001, though taken from a slightly different and higher viewpoint, somewhere around the Trogler. The triangular buttress almost dead center, above, has only its right hand side visible.
Unfortunately back in 2001 I took no great pains to make a pic I could compare against later. My map, which dates originally from 1970 but had the ice revised in 1995, shows the area as one continuous glacier with no rock.
Browsing the web, here’s one from 1980:
Here’s another view of the same, taken looking the other way from about the moraine on the far left edge of the top pic; the lack of snow in the first pic of the pair makes the difference even starker. Again, top is 2014.
And then 2001:
