One of the most interesting spots to visit, for obtaining a view of this character of scenery, is near the town of Shoals, on the road to the Indian Sulphur Springs. A high ridge of millstone grit, here, terminates within a few yards of the East Fork of White river, from the top of which, there is a projecting mass of conglomerate sandstone, called the "Pinnacle," which stands one hundred and seventy feet above the level of the stream. Cyclopean blocks, that have broken off, lie around the foot of the ridge, in every conceivable position. On the north side of this ridge, the conglomerate has been cut through by disintegrating forces, which left, at some distance from the main ledge, a tall mass of rock, which has received the name of "Jug Rock," from the fancied resemblance which it bears to a jug. It is forty-two feet high and supports, on its top, a flat projecting layer, which is called the "stopper." Just above the bulge of the jug are irregular lines of stratification, known as false bedding. The lower part is thickly set with quartz pebbles. The frontispiece to this volume presents a view of the "Jug Rock" which was copied from a photograph taken by D. Allbright. For this faithful representative of a highly interesting geological scene, I am indebted to B. F. Devol, and D. Allbright, of Shoals.
