..and Tuor saw that they stood at the end of a ravine, the like of which he had never before beheld or imagined in his thought, long though he had walked in the wild mountains of the North;for beside the Orfalch Echor Cirith Ninniach was but a groove in the rock. Here the hands of the Valar themselves, in ancient wars of the world's beginning, had wrested the great mountain asunder, and the sides of the rift were sheer as if axe-cloven, and they towered up to heights unguessable.

Though I must say the swedish version has a better "sting" in the Orfalch Echor part. They use the word "rispa" in swedish (scratch). Moria is fascinating, same goes for the City of Gondolin. Doriath is nice.
