Alberto Angela talks about how Mont Blanc was formed over millennia, and concludes this episode with a breathtaking view, as well as some lines from a poem by Shelley. Here is the original English:
Far, far above, piercing the infinite sky,
Mont Blanc appears,—still, snowy, and serene—
In the calm darkness of the moonless nights,
In the lone glare of day, the snows descend

[Or] the star-beams dart through them:—Winds contend
Silently there, and heap the snow with breath
Rapid and strong, but silently! Its home
