Mammoth Cave, Kentucky
The Mammoth Cave is a US national park which encompasses 52,830 acres in south-central Kentucky. As of 2010, more than 420 miles of passageways have been surveyed and is nearly twice as long as the second longest cave system, the Sac Actun in Mexico,
The national park was established on 1 July 1941. It was named a World Heritage Site on October 27, 1981, an international Biosphere Reserve on September 26, 1990, and an International Dark Sky Park on October 28, 2021.
World′s Longest Cave
Located in South Central Kentucky, this is a stream carved limestone cave including the Flint Ridge cave system and Mammoth cave system. By 1972, the integrated cave system contained 144.4 miles of surveyed passages and have fourteen entrances.
Further explorations during September 1983 resulted in the total surveyed length of almost 300 miles. By March 2005, incremental discoveries into the Roppel Cave portion added to the total which is now more than 400 miles.
It remains certain that more miles of cave passages will be found and despite the fact that the discovery of new natural entrances is a rare event, the primary mode of the discovery of new passage is by routine systematic exploration of side passages identified during previous explorations.
The Formation of Mammoth Cave
About 280 million years ago, during the
Permian Period water flowing out from a continent forms a large delta of sand and silt which later compacts into a slanted layer of mixed sandstone and shale. This mixed layer was deposited above a previously deposited 600 foot layer of limestone, one that was deposit much earlier (about 350 million years ago) during the
Carboniferian Period.
This earlier layered limestone was created from deposits into an ancient shallow, warm sea bed. Yes, it was into that ancient warm water, that the hard body parts of dying sea creatures, made mostly of calcium carbonate, settled into the deposits of mud on the sea bottom, after which subsequent pressure and heat transformed these deposits of creatures and sediment into limestone.
Long after the Permian Period, the entire North American continent rose and subsequent rainfall would seep through the earth and that water would slowly wash away the easily dissolved limestone as it travels underground. This rain water would form streams, then rivers and even large caverns in the limestone.
Meantime, the above sandstone and shale, which are much more resistant to being dissolved by water, served as a caprock to the newly forming streams beneath and eventually became the roof of this ever growing cavern system.
The entire Mammoth Cave plateau is filled with a large network of hundred of miles of streams which have carved many caves. Mammoth Cave is the most famous cave beneath this plateau and is the longest cave in the world.
