Polar Pathways: Robert E. Peary's Arctic Expeditions
The North Pole - One Day from the Pole
"We slept only a few hours the next night, hitting the trail again a little before midnight between the 3d and 4th of April. The weather and the going were even better than the day before. The surface of the ice, except as interrupted by infrequent pressure ridges, was as level as the glacial fringe from Hecla to Cape Columbia, and harder. I rejoiced at the thought that if the weather held good I should be able to get in my five marches before noon of the 6th. Again we traveled for ten hours straight ahead, the dogs often on the trot and occasionally on the run, and in those ten hours we reeled off at least twenty-five miles." - Robert E. Peary in The North Pole, published in 1910
