“Chamouni, July 25th. We have returned from visiting the glacier of Montanvert, or as it is called, the Sea of Ice, a scene in truth of dizzying wonder. The path that winds to it along the side of a mountain, now clothed with pines, now intersected with snowy hollows, is wide and steep. The cabin of Montanvert is three leagues from Chamouni, half of which distance is performed on mules, not so sure-footed but that on the first day the one which I rode fell in what the guides call a mauvaispas, so that I narrowly escaped being precipitated down the mountain. We passed over a hollow covered with snow, down which vast stones are accustomed to roll. One had fallen the preceding day, a little time after we had returned: or guides desired us to pass quickly, for it is said that sometimes the least sound will accelerate their descent. We arrived atMontanvert, however, safe. On all sides precipitous mountains, the abodes of unrelenting frost, surround this vale: their sides are banked up with ice and snow, broken, heaped high, and exhibiting terrific chasms. The summits are sharp and naked pinnacles, whose overhanging steepness will not even permit snow to rest upon them. Lines of dazzling ice occupy here and there their perpendicular rifts, and shine through the driving vapours with inexpressible brilliance: they pierce the clouds like things not belonging to this earth. The vale itself is filled with a mass ofundulating ice, and has an ascent sufficiently gradual even to the remotest abysses of these horrible deserts. It is only half aleague (about two miles) in breadth, and seems much less. It exhibits an appearance as if frost had suddenly bound up thewaves and whirlpools of a mighty torrent. We walked some distance upon its surface. The waves are elevated about twelve or fifteen feet from the surface of the mass, which is intersected by long gaps of unfathomable depth, the ice of whose sides is more beautifully azure than the sky. In these regions everything changes, and is in motion. This vast mass of ice has one general progress, which ceases neither day nor night; it breaks and bursts forever: some undulations sink while others rise; it is never the same. The echo of rocks, or of the ice and snow which fall from their overhanging precipices, or roll from their aerial summits, scarcely ceases for one moment. One would think that Mont Blanc, like the god of the Stoics, was avast animal, and that the frozen blood forever circulated through his stony veins.
We dined (M***, C***, and I) on the grass, in the open air, surrounded by this scene. The air is piercing and clear. Wereturned down the mountain, sometimes encompassed by the driving vapours, sometimes cheered by the sunbeams, and arrived at our inn by seven o’clock.”
