We arrived that evening, after many hardships and adventures, in some fields close to the great ice-arch where the mad Visp boils and surges out from under the foot of the great Gorner Glacier, and here we camped, our perils over and our magnificent undertaking successfully completed. We marched into Zermatt the next day, and were received with the most lavish honors and applause. A document, signed and sealed by the authorities, was given to me which established and endorsed the fact that I had made the ascent of the Riffelberg. This I wear around my neck, and it will be buried with me when I am no more. CHAPTER XL [Piteous Relics at Chamonix] I am not so ignorant about glacial movement, now, as I was when I took passage on the Gorner Glacier. I have "read up" since. I am aware that these vast bodies of ice do not travel at the same rate of speed; while the Gorner Glacier makes less than an inch a day, the Unter-Aar Glacier makes as much as eight; and still other glaciers are said to go twelve, sixteen, and even twenty inches a day. One writer says that the slowest glacier travels twenty-five feet a year, and the fastest four hundred. What is a glacier? It is easy to say it looks like a frozen river which occupies the bed of a winding gorge or gully between mountains. But that gives no notion of its vastness. For it is sometimes six hundred feet thick, and we are not accustomed to rivers six hundred feet deep; no, our rivers are six feet, twenty feet, and sometimes fifty feet deep; we are not quite able to grasp so large a fact as an ice-river six hundred feet deep. The glacier's surface is not smooth and level, but has deep swales and swelling elevations, and sometimes has the look of a tossing sea whose turbulent billows were frozen hard in the instant of their most violent motion; the glacier's surface is not a flawless mass, but is a river with cracks or crevices, some narrow, some gaping wide. Many a man, the victim of a slip or a misstep, has plunged down one of these and met his death. Men have been fished out of them alive; but it was when they did not go to a great depth; the cold of the great depths would quickly stupefy a man, whether he was hurt or unhurt. These cracks do not go straight down; one can seldom see more than twenty to forty feet down them; consequently men who have disappeared in them have been sought for, in the hope that they had stopped within helping distance, whereas their case, in most instances, had really been hopeless from the beginning.
