The continental glacier moves down to the sea, regularly but slowly; the rate of movement of some portions of the adjacent coastal ice cliffs was found to be one hundred feet per annum. The rocky promontory at Winter Quarters, acting as an obstacle, reduces the motion of the ice to an annual rate measured in inches only. Perhaps the conditions now prevailing are those of a comparative "drought," for there is clear evidence that our small promontory was at one time completely enveloped. In a broad way this is illustrated by the topography, but the final proof came when Stillwell and others discovered rock-faces polished and grooved by the ice. Whatever "ice-floods" there may have been in the past, the position of the margin of the glacier must have remained for a long period in its present situation. The evidence for this is found in the presence of a continuous, terminal moraine, at or just in advance of the present ice-front. This moraine, an accumulation of stones of all kinds brought to their present resting-place by the ice-sheet, was in itself a veritable museum. Rocks, showing every variety in colour and form, were assembled, transported from far and wide over the great expanse of the continent. [TEXT ILLUSTRATION] A section of the coastal slope of the Continental Ice Sheet inland from Winter Quarters, Adelie Land Stillwell found these moraines a "happy hunting-ground" for the geologist. His plane-table survey and rock collections are practical evidence of work carried out in weather which made it seldom short of an ordeal. The story of the buried land to the south is in large measure revealed in the samples brought by the ice and so conveniently dumped. Let us swiftly review the operations leading to the deposition of this natural museum. As the ice of the hinterland moves forward, it plucks fragments from the rocky floor. Secure in its grip, these are used as graving-tools to erode its bed. Throwing its whole weight upon them it grinds and scratches, pulverizes and grooves. The rocky basement is gradually reduced in level, especially the softer regions. The tools are faceted, polished and furrowed, for ever moving onwards. Finally, the rock-powder or "rock-flour," as it is termed, and the boulders, thenceforth known as "erratics," arrive at the terminal ice-face. Here, the melting due to the sun's heat keeps pace with the "on-thrust" and some of the erratics may remain stationary, or else, floating in the sea, a berg laden with boulders breaks off and deposits its load in the depths of the ocean. Each summer the ice-face above the rocks at Winter Quarters thawed back a short distance and the water ran away in rivulets, milky-white on account of the "rock-flour" in suspension. The pebbles and boulders too heavy to be washed away remained behind to form the moraine.
