The area in the above photo, right below the outcrop that splits the ice/snow chute in two, was where Osborn and Bevis (2001) saw and photographed a bergschrund. It's not visible above - could it be covered by snow still left in early July? Or could there be one lower down, below the highest ridge of the rock glacier?
Above, a photo taken just to the right of the previous one, showing the steep, cirque headwall made of layered Prospect Mountain Quartzite, with Wheeler Peak right at the top of it all.
Below, two photos with a closer view of the distorted bedding in the quartzite. Judging from some striated to slickensided surfaces on thin, dark shaly faces of quartzite blocks in the rock glacier, I suspect some bedding-parallel slip of some sort.
1) The photo above shows the lower, light-colored, quartzite near the base of the cirque headwall with some distortion along a contact with part of an overlying section of darker quartzite. 2) Above, higher still in the cliff, the darker layers show more distorted bedding and some folding.
