The English photographer Simon Norfolk spent 18 days on Mount Kenya, this past October, camping in an old mountaineering hut at nearly 16,000 feet. Photographer was there to document the gradual disappearance of the mountain glacier, the Lewis, a tropical glacier in Africa. “He overlaid GPS coordinates onto that historical data about the Lewis Glacier’s size and shape. This allowed him to plot out the vanished edges of the glacier on the actual landscape. He then slowly walked those lines, in the middle of the night, with a makeshift torch: a length of shaggy white carpet rolled into a wick, soaked in gasoline, strapped to a garden rake.” more about Disappearance of the glacier on the New York Timeswebsite.
