The Germans, Scandinavians, Poles and Hungarians, energetic as they were, had never held their own against the heterogeneous mass of inertia called Russia, and trembled with terror whenever Russia moved. From Stockholm one looked back on it as though it were an ice-sheet, and so had Stockholm watched it for centuries. In contrast with the dreary forests of Russia and the stern streets of St.
At 4 a.m. on the 16th we reached the edge of another huge glacial overflow from the ice-sheet. The ice appeared to be coming over low hills and was heavily broken. The cliff- face was 250 to 350 ft. high, and the ice surface two miles inland was probably 2000 ft. high. The cliff-front showed a tide-mark of about 6 ft., proving that it was not afloat.
These so-called "kettles" were formed by the melting of large detached blocks of ice that had been buried in moraine material thousands of years ago when the ice-sheet that covered all this region was receding.
William stopped the procession before we reached the bad stretch and went hastily over a part of it. Under his single weight we could see the ice-sheet undulating. It had been our rule that ice was not safe unless it took three blows of the axe to bring water, but this ice gave water at a blow. When William returned he made quite an harangue, which Arthur interpreted.
In one hundred thousand years what changes should we probably find? Here in the Catskills, where I write, the weathering of the hills and mountains would probably have been but slight. It must be fifty thousand years or more since the great ice-sheet left us.
In the same way we may trace the southern border of our ancient ice-sheet on this continent by the limit of the boulders; beyond that line it evidently did not advance as a solid mass, since it ceased to transport the heavier materials.
Barne also obtained a very good indication of the movement of the Great Barrier ice-sheet. During Royds' journey, on which the party went on very short food allowance, Bernacchi took a most interesting series of magnetic observations.
The range dipped opposite the bay into a well- defined pass from east to west. An ice-sheet covered most of the interior, filling the valleys and disguising the configurations of the land, which, indeed, showed only in big rocky ridges, peaks, and nunataks.
One could break a circuit with an accuracy of microseconds, but that wouldn't be close enough for overdrive. It wouldn't be practical. Then the ice-sheet of Tralee's nearest neighbor planet spread out in the vision-port's range of view. Bors called for the cargo-ship. It answered almost immediately.
In the course of my studies I observed that the northern groves, the only ones I was at first acquainted with, were located on just those portions of the general forest soil-belt that were first laid bare toward the close of the glacial period when the ice-sheet began to break up into individual glaciers.
