I saw one of the tractors that Hillary used to make his trek from the coast to the pole. It's amazing that he would do such a thing on such tiny little tractors. This one fell into a hidden crevass.
Hillary is a really amazing guy and has done a lot of good in Nepal, but he has not tread lightly on this planet. Driving tractors across fragile polar ecosystems, jet-boating up the Ganges from the sea to the source, dropping oxygen bottles all over the side of Everest. He has done more than many to open up the wild regions of the planet to the teeming masses. He has little right to complain that others have followed him.
