The Susquehanna at Monocasy Island. This view is from the left of eastern bank of the Susquehanna, opposite the center of Monocasy Island, looking up the river. Toward the foreground, on the right of the picture, a little beyond the bar-post, is seen a ravine, through which the fugitives who crossed the river in safety made their way. On the left are seen the upper end of Monocasy, and a sand-bar which divides the waters of the river. The distant hills on the left are those which bound the western side of the valley. From the head of Monocasy Island, across the sand-bar, the river is often fordable in summer to the eastern side.
