View of the Taylor Glacier -- a river of flowing ice as far as the eye can see. View is looking up-valley to the east. Striations on the ridges in the distance of Taylor Valley (dark/light bandings) are just visible (Dry Valleys, Antarctica).

Platelets formed in a snowfield by old "dirty ice" (probably wind-blown dirt) attracting heat and causing the ice to evaporate slightly, in pockets, as it flows.
