Check out the toll a hundred years of global warming can take on a fragile Sierra glacier. This photographer is going all over the Sierra taking photos of all the glaciers for comparison with historical photos. In the video below, he describes his process and then captures an image of the Dana glacier.
The Dana Couloir above the glacier, incidentally, is a killer ice climb in the fall and an awesome ski descent in the winter/spring. The trailhead is near Tioga Pass on the east side of Yosemite. If you haven't been, I'd highly recommend you go check this out yourself. It's gorgeous up there.
