Jefferson overlooking Harpers Ferry, 25 October 1783

The passage of the Potomac, through the Blue Ridge, is perhaps one of the most stupendous scenes in nature. You stand on a very high point of land. On your right comes up the Shenandoah, having ranged along the foot of the mountain a hundred miles to seek a vent. On your left approaches the Potomac, seeking a passage also.

Jefferson had a lithograph of this painting.

The same view today, approximate time of year Jefferson visited.

In the moment of their junction, they rush together against the mountain, rend it asunder, and pass off to the sea. The first glance at this scene hurries our senses into the opinion, that this earth has been created in time; that the mountains were formed first; that the rivers began to flow afterwards; that, in this place particularly, they have been dammed up by the Blue Ridge of mountains, and have formed an ocean which filled the whole valley; that, continuing to rise, they have at length broken over at this spot, and have torn the mountain down from its summit to its base. The piles of rock on each hand, but particularly on the Shenandoah, the evident marks of their disrupture and avulsion from their beds by the most powerful agents of nature, corroborate the impression. But the distant finishing, which Nature has given to the picture, is of a very different character. It is a true contrast to the foreground. It is as placid and delightful as that is wild and tremendous. For, the mountain being cloven asunder, she presents to your eye, through the cleft, a small catch of smooth blue horizon, at an infinite distance in the plain country, inviting you, as it were, from the riot and tumult roaring around, to pass through the breach, and participate of the calm below. Here the eye ultimately composes itself; and that way, too, the road happens actually to lead. You cross the Potomac above its junction, pass along its side through the base of the mountain for three miles, its terrible precipices hanging in fragments over you, and within about twenty miles reach Fredericktown, and the fine country round that. This scene is worth a voyage across the Atlantic. Yet here, as in the neighborhood of the Natural Bridge, are people who have passed their lives within half a dozen miles, and have never been to survey these monuments of a war between rivers and mountains, which must have shaken the earth itself to its centre.
