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."
Howe tells us, that in Washington County, "westerly from Abingdon,
between Three Springs and the North Fork of Holston, on Abram's Creek,
in a narrow, gloomy ravine, bounded by a high perpendicular ledge, is a
large waterfall, which in one single leap descends perpendicularly 60
feet, and then falls about 40 feet more ere it reaches the bottom. The
stream is about 20 feet wide."
