To the north-west, behind us, a projecting ridge of rock--Madigan Nunatak--came into sight. From the camp of the previous evening it had evidently been hidden from view by an undulation in the surface. During the afternoon it was noted that the surface had become very deeply eroded by the wind, troughs three feet in depth being common, into which the sledges frequently capsized. Each of us took it in turn to run ahead, jumping from one sastruga to another. As these were firm and polished by the constant wind, one often slipped with a sudden shock to the ground. Our bodies were well padded with clothing and we were beginning to get into good form, so that these habitual tumbles were taken with the best grace we could muster. I surprised myself during the afternoon, when my turn came as forerunner, by covering two and a half miles at a jog-trot without a break. The grade was slightly downhill and the sledges moved along of their own accord, accelerated by jerks from the dogs, gliding at right angles to the knife-edge crests of the snow-waves. The roughness of the surface was not without its effect on the sledge-meter, which had to be repaired temporarily. It was a matter of some inconvenience that after this date its records were erroneous and approximate distances were only obtained by checking the readings against absolute observations made for latitude and longitude. At 5.30 P.M. a dark object stood in salient relief above the white contour of the snowy sky-line on the right. Suppressing our excitement, we pressed on eagerly, changing course so as to approach it. At nine o'clock it resolved itself into the summit of an imposing mountain rising up from a mysterious valley. Aurora Peak, as it was named, was to be a prominent landmark for several days to come. All were ready to be on the move at 8.45 A.M. on November 19. While Mertz and Ninnis built a cairn of snow, I wrote a note to be left on it in a tin, containing instructions to Stillwell in case he should happen on the locality. The weather was good and the temperatures were high, ranging at this time (one month from midsummer) between zero and 18 degrees F. When we camped for lunch the air was quite calm and the sun's rays were extremely warm. The surface became softer and smoother as the afternoon lengthened until Mertz was tempted to put on his skis. He then became forerunner for the remainder of the day. Mertz, who was skilled in the use of skis, found them of great service on this and on many future occasions. At such times he would relieve Ninnis and myself in the van. On the other hand, over deeply furrowed sastrugi or blue ice, or during a strong wind, unless it were at our backs, skiing was impossible.
