which is peculiar to them, quite distinct even from the reality of their unutterable greatness.
Yesterday morning we went to the source of the Arveiron.

The glacier by which its waters are nourished, overhangs this cavern and the plain, and the forests of pine which surround it, with terrible precipices of solid ice. On the other side rises the immense glacier of Montanvert, fifty miles in extent, occupying a chasm among mountains of inconceivable height, and of forms so pointed and abrupt, that they seem to pierce the sky. From this glacier we saw as we sat on a rock, close to one of the streams of the Arveiron, masses of ice detach themselves from on high, and rush with a loud dull noise into the vale.
