context_page_description: Jug Rock is a natural geological formation located outside of Shoals, Indiana, in the valley of the East Fork of the White River. It is composed of sandstone, and is the largest free-standing table rock formation in the United States east of the Mississippi River. It is part of the Mansfield formation, laid down in the Pennsylvanian geological epoch, roughly 325 to 286 million years ago. Erosion along fracture lines separated it from a nearby cliff. A companion feature, House Rock, stands opposite Jug Rock.
