Perhaps its most famous explorer, Stephen Bishop, described the cave as "grand, gloomy, and peculiar."
The park's 52,830 acres (214 kmē) is located in Edmonson County, Kentucky, with small areas extending eastward into Hart County and Barren County. It is centered around the Green River, with a tributary, the Nolin River, feeding into the Green just inside the park. The Green River is dammed near the western boundary of the park, so that the river only flows freely for a small section in the eastern part of the park.
Almost two million people visit the park every year.
Mammoth Cave is a system in thick limestoneshale overlaid by limestone. Cumberland Plateau, Tennessee Limestone is a sedimentary rock composed of mineral calcite (calcium carbonate). The primary source of this calcite is usually marine organisms. These organisms secrete shells that settle out of t strata capped by a layer of sandstoneSandstone is an arenaceous sedimentary rock composed mainly of feldspar and quartz and varies in colour (in a similar way to sand), through grey, yellow, red, and white. Since sandstones often form highly visible cliffs and other rock formations, certain, making the system remarkably stable. It currently comprises over 365 miles of passageway, with new discoveries and connections adding several miles per year to this figure. The cave was a significant source for saltpeter production for the manufacture of gunpowderGunpowder is a substance which burns very rapidly and is used as a propellant in firearms. There are two types: Black powder, which was discovered in the 9th Century and as the only known practical explosive was widely used until the 20th Century. However at one time, especially in the War of 1812The North American War of 1812 between the United States and the United Kingdom is one of several wars associated with that year. It is more normally known in British texts as the British-American War to distinguish it from Napoleon's war against Russia w.

Many countries have laws offering special protection to these species (forbidding hunting, banning their habitats from development, etc. to prevent t Kentucky cave shrimp, a sightless, pigmentless shrimp found in only three counties of Kentucky.
