The lighting was dramatic at times, due to some puffy cumulus clouds that developed in the afternoon. I took a few pictures as the lighting changed, first some shadows here, then there, shadows moving all around. In the photo above, you can see the rock piles of the lower part of the rock glacier in the foreground, with the cirque headwall of Wheeler Peak (that's the peak!) in the background.
Above, more of the interesting lighting, showing the ice/snow chutes above the glacier.
Oh hey, we came upon this neat little glacial lake (or pond), just before starting the climb to the upper part of the rock glacier. The water and melting ice or snow fills some small, irregular depressions in the lumpy rock glacier.
I don't really know if this qualifies as a glacial lake, since the water is on a rock glacier and not on a glacier, but the color of the water is the milky turquoise blue typical of water containing rock flour created by glaciers. Of course, there should be plenty of rock flour in this glacial valley. The color, therefore, doesn't necessarily indicate that the water is coming from melting glacial ice. The presence of this tiny lake or pond could, however, be an indication of stagnation, either from the melting of ice within or beneath the rock glacier, or from the melting of the small glacier at the base of the cirque headwall. I don't really know how to test these ideas out without some kind of drilling (not likely), but I'm on my way upward to the upper part of the rock glacier so can't stay and ponder these questions for very long.
