'Narrows near Lewistown', 1874. The Juniata River, Pennsylvania, USA. 'The hills on both sides, that have hitherto been so amiable, suddenly break off, and the great wall comes into view on the right hand, while on the left we get the side of a mountain instead of its front. On both banks the hills are remarkably steep, and they approach so closely together as to confine the little river within extremely narrow bounds. For seven miles and a half this imprisonment lasts; and here, perhaps, the mountains show their grandest forms. The bases are often crag-like, showing huge masses of stone that seem to hang on to the side without any definite support, and threaten momentarily to come down upon one's head'.
