The glacière is in the middle of a pasture, with several pine trees overhanging it. It is surrounded by a wall, built to prevent the cows from falling in. There are two pits, side by side and about three meters apart: they are some thirteen meters in depth, with a width of five or six meters. They open into one another at the bottom; the rock separating them, forming a natural bridge overhead. One of the pits is vertical on all sides. The other is vertical all around, except on the side furthest away from the natural bridge. Here the side of the pit is in the shape, so usual in glacières, of a steep slope. Down this slope we descended. It was slippery and muddy, owing to the recent heavy rains, and my ice axe proved invaluable and probably saved me some unpleasant falls. Under the bridge, the floor was covered with a mass of shattered limestone debris, among which there was neither ice nor snow; both of which my guide said he had found in abundance the preceding June. A little limestone cavern opened on one side below the bridge. A great, flat limestone slab formed a natural lintel, and, lighting our candles, we stooped down and passed under it into the cave, which was about the size of a room and in which we could just stand up. At the entrance and over most of the floor there was ice, in one place thirty or forty centimeters in depth, as I could see where a drip from the roof had cut a hole. There were no signs of icicles or columns. My guide said he had never penetrated into this chamber, which he thought, on his earlier visit, was blocked with ice and snow. I did not see any limestone stalactites anywhere, and I am inclined to think that the low temperatures of glacières have a tendency to prevent their formation. After our visit, we went to the Châlet de La Genollière close by, where there were some thirty cows and calves. The intelligent _berger_ or manager said that most of the ice from the glacière was used for butter making during the hot weather; and that between the inroads thus made upon it and from other causes, the ice disappeared every year before autumn, but that it formed afresh every winter; pretty good evidence to show that the ice in this cave has nothing to do with a glacial period. He also stated that when he first entered the inner chamber in the spring there were four ice columns there.
