that they were definitely underpowered for day-in and day-out Barrier travel. The fourth was a 20-40 Cletrac, made in the United States. All were short; all, particularly the six-ton Cletrac, were heavy, which shortcomings made them vulnerable to crevasses.
So the trip was a gamble, no matter how I looked at it. This was the first serious attempt to operate automotive equipment in the Antarctic; the risks were the inevitable risks of pioneering. No one could tell how well the engines would function in temperatures down to 60 degrees below zero or how the caterpillar treads would work on a snow surface which cold granulates to the fineness of sand or whether the machines could penetrate crevassed areas. If the fleet made a southing of 200 miles, it would be performing a miracle, I decided. And I was ready to settle for 150 miles -- less, if necessary, so long as the journey could be made without undue hardships for the men.
Yet, we were not allowed to prepare in peace. When I recall the events that preceded the start, I wonder that we came off with a little damage as we did. Young John Dyer, Chief Radio Engineer, plunged forty-five feet from the top of an antenna pole, with no worse hurt than a barked shin. Rawson, the Navigator, had to be operated on for a streptococcus throat infection. Then Pelter, the Aerial Photographer, came down with appendicitis; this meant another hasty operation under conditions made melodramatic by the doctor's unwitting act. Knocking over a lamp, he set fire to the cache in which all the surgical instruments were stored; all hands were wildly mustered to save the instruments and a dozen sleeping men who were in danger of being trapped in the adjoining shack. And this happened just a day or so after the Fokker had crashed in full view of the camp, and four men, stunned but otherwise unhurt, had crawled out from the wreckage.
Breaking rapidly one on top of the other, these incidents, any one of which might have been fatal, rasped nerves already drawn taut by the exhausting demands of Misery Trail. We were ready to find anything under the bed. In this mood we jumped one day to the grim conclusion that Little America was on the verge of breaking loose from the Antarctic Continent and drifting into the Ross Sea as a calving iceberg.
Little America is actually a city on a raft. The 300-foot thickness of ice on which it rests is pocketed in the coastal reach of the Ross Ice Barrier, whose sheer cliffs in places rise to 150 feet above sea level. Partly floating free, partly resting on deep submarine reefs and shoals, and elsewhere riding over the land, this gigantic Barrier fronts the ocean for 400 miles and also extends inland clear to the foot of the Queen Maud Mountains. It is not fixed in the sense that land is fixed. It is, in effect, an enormous glacier, wide enough to blanket the Atlantic seaboard States, and, like a glacier, it is forever creeping toward the sea. Propelled from behind by the massive rivers of ice pouring down through the mountain passes from the polar plateau, the coastal edges tend to bulge out over the sea, until the sheer weight of the projecting shelf or the violent pressures of tide and storm cause great strips to break off.
In this way the vast fleets of icebergs which patrol the ocean approaches to Antarctica are created. We had seen these products of continental disintegration. In the course of the voyage through the Devil's Graveyard, far to the north and east of Little America, we had counted no less than 8,000 bergs in a single day, some of them twenty miles long. I don't think that any of us will ever forget what it was like in the Devil's Graveyard: the sunless corridors of waste waters; the fog that sometimes thinned but never lifted; the crash of the gales, and occasionally over that uproar the heavier sound of bergs capsizing in the storm; and everywhere those stricken fleets of ice, bigger by far than all the navies in the world, wandering hopelessly through a
