G. F. Browne, Ice-Caves of France and Switzerland
“ This outer cave presents a curious appearance, from the distinctness with which the several strata of the limestone are marked, the lower strata weathered and rounded off like the seats of an amphitheatre of the giants, and all, up to the shell-like roof, arranged in horizontal semicircles of various graduated sizes, showing their concavity; while at the bottom of the whole is seen a patch of darkness, with two masses of ice in its centre, looming out like grey ghosts at midnight. ”
