ravines

And I went beyond it and saw seven magnificent mountains all differing each from the other, and the stones (thereof) were magnificent and beautiful, magnificent as a whole, of glorious appearance and fair exterior: three towards the east, one founded on the other, and three towards the south, one upon the other, and deep rough ravines, no one of which joined with any other.

And all the ravines were deep and narrow, (being formed) of hard rock, and trees were not planted upon them.

The country is encircled by a natural fence and is very difficult to attack and cannot be assailed by large forces, owing to the narrow passes, with theft overhanging precipices and deep ravines, and the rugged character of the mountainous regions which surround all the land.
