Top left of the photo .. there is dark stuff in the cavities .. the dark stuff appears to be the same dark stuff as the flow. What flows when it is dry? Would powdered carbon flow like that? Where might that powdered carbon come from? The stuff seems to flow without causing erosion as liquid would. Buckeyball stuff?

Donald Ritchie, record-setting ultrarunner, dies at 73
by Phil Davison, Washington Post June 28

<<Donald Ritchie became the United Kingdom’s greatest “ultrarunner” and one of the best in the world. He set international records for distances from 50 kilometers to 200 kilometers and in time-based races of up to 24 hours. Asked about the secrets of ultrarunning, Mr. Ritchie admitted he never stopped at the portable toilets but preferred to urinate while running. It saved him vital minutes or seconds, he said, and dehydration meant that no one but he would probably notice.>>
