I am not sure of the catorgey for this one. My wife and I just returned from Mammoth Cave where I took this pic of a stalagmite that had been cut off about 6 inches from the ground undoubled decades ago being the cave is Nationally protected.
Stalagmite Cross-section from Mammoth Cave
From Wikipedia, the free encyclopedia
A stalagmite (from the Greek stalagma ("Σταλαγμίτης"), "drop" or "drip") is a type of speleothem that rises from the floor of a limestone cave due to the dripping of mineralized solutions and the deposition of calcium carbonate.
Mammoth Cave National Park is a U.S. National Park in central Kentucky, encompassing portions of Mammoth Cave, the most extensive cave system known in the world. The official name of the system is the Mammoth Cave System, though it could be argued that it should be called the Flint-Mammoth-Toohey-Eudora-Joppa-Jim Lee Ridge Cave System—to account for the ridges under which the cave has formed. The park was established as a national park on July 1, 1941. It became a World Heritage Site on October 27, 1981, and an international Biosphere Reserve on September 26, 1990. The park's 52,830 acres (214 km˛) 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 developed in thick Mississippian-aged limestone strata capped by a layer of sandstone, making the system remarkably stable. It is known to include more than 360 miles (579 kilometers) of passageway; new discoveries and connections add several miles to this figure each year.
In partnership with Valentine Simon, various other individuals would own the land through the War of 1812, when Mammoth Cave's saltpeter reserves became significant due to the British blockade of United States's ports. The blockade starved the American military of saltpeter and therefore gunpowder. As a result, the domestic price of saltpeter rose and production based on nitrates extracted from caves such as Mammoth Cave became more lucrative. |

This pic turned out magnificantly! The colours show up so clear especially because this pic would have had to be taken in the dark. Using the 'outside' of the stalagmite and the surrounding cave stone shows how incredible the formation of a stalagmite is. Very stunning!
