Read it through once

I passed the bridge of Pélissier, where the ravine, which the river forms, opened before me, and I began to ascend the mountain that overhangs it. Soon after, I entered the valley of Chamounix. This valley is more wonderful and sublime, but not so beautiful and picturesque as that of Servox, through which I had just passed. The high and snowy mountains were its immediate boundaries, but I saw no more ruined castles and fertile fields. Immense glaciers approached the road; I heard the rumbling thunder of the falling avalanche and marked the smoke of its passage. Mont Blanc, the supreme and magnificent Mont Blanc, raised itself from the surrounding _aiguilles_, and its tremendous _dôme_ overlooked the valley.
