A river of ice, under the right conditions, flows as literally as a river of water, fastest in the middle, and slowest along its margins where the friction is greatest. The old ice-sheet, or ice sea, flowed around and over mountains as a river flows around and over rocks. Where a mountain rose above the glacier, the ice divided and flowed round it, and reunited again beyond it.
Many striking examples of these successive processes may be seen in the Tahoe region, as, for instance, Squaw Valley, which lies between the spurs of Squaw Peak and Granite Chief. This was undoubtedly scooped out by a glacier that came down from Squaw Peak and Granite Chief. The course of the ice-sheet was down to the Truckee River.
At this southern end of the Caird Coast the ice-sheet, undulating over the hidden and imprisoned land, is bursting down a steep slope in tremendous glaciers, bristling with ridges and spikes of ice and seamed by thousands of crevasses. Along the whole length of the coast we have seen no bare land or rock. Not as much as a solitary nunatak has appeared to relieve the surface of ice and snow.
This great ice-sheet not only covered our northern farms with rocks and stones, and packed the soil with rounded boulders, but it also carried away much of the rock decay that goes to the making of the soil, so that the soil is of greater depth in the non-glaciated than in the glaciated areas of the country.
And out on the lake itself the frost is at work, and the ice-sheet is forming, and under that cold, white lid the Glimmerglass will wait till another year brings round another spring-time the spring-time that will surely come to all of us if only we hold on long enough. Chicago, December, 1901.
Had the ice-sheet that once covered all the range been melted simultaneously from the foot-hills to the summits, the flanks would, of course, have been left almost bare of soil, and these noble forests would be wanting.
I have often thought that that cold winter was a fore-runner of the countless cold winters to come, as the ice-sheet from farther north crept down over the face of the land. But we never saw that ice-sheet. Many generations must have passed away before the descendants of the horde migrated south, or remained and adapted themselves to the changed conditions.
After the last great extension of glaciers in Europe, during which nearly all of Great Britain and the North of France and Germany were buried with Scandinavia under one great ice-sheet and when this ice-sheet had receded, and the climate was like that of the Russian "steppes," cold and dry there were men inhabiting the caverns on both sides of the Pyrenees.
It is also said that we cannot on these principles understand the repeated advance and retreat of the ice-sheet. This objection, again, seems to fail. It is an established fact that the land sank very considerably during the Ice-Age, and has risen again since the ice disappeared. Here we have the possibility of an explanation of the advances and retreats of the glaciers.
He shifted the box, and the landscape image flashed sidewise. He touched another control. The landscape flowed swiftly toward the viewer. It raced. Presently the ground seemed to drop away and Soames found himself staring at a picture which showed the ice-sheet and the sky and very far away the dark blue line which was the sea, now a hundred miles distant.
