On our return, we chose a thinner section of the Muldrow moraine to cross, affording us a comparatively rapid scamper across delightfully barren ice.
For those that are curious, no, that's not the natural thickness of my legs. Underneath the rather bulky North Face Rain Pants is an even bulkier REI pile insulating pants layer, itself over a pair of cutoffs.
Why the layering? True, the sun was shining uncommonly bright (~65-76 F on the gravel hills behind me), reflecting off the ice around us and we kept more than warm enough while we were moving. However, as soon as we stopped - and particularly when a breeze was blowing down the glacier - it had a surprising ability to chill - and quickly.
