"The grandeur and sublimity of this extraordinary work of nature, consists in its tremendous height and singular formation. On entering the mouth of the fort, we are struck with the awful height of the mountains on each side, probably not less than a thousand feet. Through a very narrow passage, a bold and beautiful stream of water rushes, called Passage Creek, which a short distance below works several fine merchant mills. After travelling two or three miles, the valley gradually widens, and for upwards of twenty miles furnishes arable land, and affords settlement for eighty or ninety families, several of whom own very valuable farms. The two mountains run parallel 24 or 25 miles, and are called East and West Fort Mountains, and then are merged into one, anciently Mesinetto, now Masinutton Mountain. The Masinutton Mountain continues its course about 35 or 36 miles southerly, and abruptly terminates opposite Keisletown, in the County of Rockingham. This range of mountains divides the two branches of the Shenandoah River, called the South and North Forks. This mountain, upon the whole, presents to the eye something of the shape of the letter Y, or perhaps more the shape of the hounds and tongue of a wagon. "A few miles above Luray, on the west side of the river, there are three large INDIAN GRAVES, ranged nearly side by side, 30 or 40 feet in length, 12 or 14 feet wide, and 5 or 6 feet high. Around them, in a circular form, are a number of single graves. The whole covers an area of little less than a quarter of an acre. They present to the eye a very ancient appearance, and are covered over with pine and other forest growth. The excavation of the ground around them is plainly to be seen. The three first-mentioned graves are in oblong form; probably contain many hundreds of human bodies, and were doubtless the work of ages. PEAK KNOB, AND THE GLASS WINDOWS. These two curiosities, in Pulaski County, are thus described by Howe: "Peak Knob, 4 miles south of Newbern, is a prominent projection in Draper's Mountain, rising about 1,000 feet, and presenting from its summit a delightful and extensive landscape. Iron ore exists in abundance in this mountain, and also coal of a good quality. In its vicinity are mineral springs, supposed to possess valuable medicinal qualities. "On the north bank of New River, near Newbern, there is a bluff called THE GLASS WINDOWS, consisting of vertical rocks nearly 500 feet high, and forming the immediate bank of the stream for a distance of four miles. They are considered a great curiosity. The face of these rocks is perforated by a vast number of cavities, which no doubt lead to caves or cells within the mountain. Some of the cells have been explored, and found to contain saltpetre, stalactites, and other concretions."
