The Mammoth Cave is situated in the County of Edmondson and State of Kentucky, equidistant from the cities of Louisville and Nashville, (about ninety miles from each,) and immediately upon the nearest road between those two places. Green River is within half a mile of the Cave, and since the improvements in its navigation, by the construction of locks and dams, steam-boats can, at all seasons, ascend to Bowling Green, distant but twenty-two miles, and, for the greater part of the year, to the Cave itself. In going to the Cave from Munfordsville, you will observe a lofty range of barren highlands to the North, which approaches nearer and nearer the Cave as you advance, until it reaches to within a mile of it. This range of highlands or cliffs, composed of calcareous rock, pursuing its rectilinear course, is seen the greater part of the way as you proceed on towards Bowling Green; and, at last, looses itself in the counties below. Under this extensive range of cliffs it is conjectured that the great subterranean territory mainly extends itself. For a distance of two miles from the Cave, as you approach it from the South-East, the country is level. It was, until recently, a prairie, on which, however, the oak, chestnut and hickory are now growing; and having no underbrush, its smooth, verdant openings present, here and there, no unapt resemblance to the parks of the English nobility.
