"When, from behind that craggy steep... a huge peak, black and huge"
-Volta (turning point) = was safe and beautiful, now scary and dangerous
-"craggy" = shatters previous delicacy of the description
-"huge peak, black and huge" = monosyllabic and opposes "glittering"/out of place in the like the mountain is in the scenery
-Repetition of "huge" = shows fear and panic
