'Tyrone Gap, View from the Bridge', 1874. The Juniata River, Pennsylvania, USA. 'The hills that lie at the base of the mountains show pleasant farm-houses and deep-green-leaved corn. The mountains...look as if they had been cleft asunder, for there is a great gap cut between two mountains. This in times past was doubtless the work of the Juniata [River], and was not so difficult as it looks; for the shaly mountains are very different from the firm limestone, through which the Kanata cuts its way at Trenton Falls'. From "Picturesque America; or, The Land We Live In, A Delineation by Pen and Pencil of the Mountains, Rivers, Lakes...with Illustrations on Steel and Wood by Eminent American Artists" Vol. II, edited by William Cullen Bryant.
