This is a list compiling caves in US state of Tennessee with Wikipedia articles. This is the most known caves of any US state, and is estimated to be around twenty percent of all caves in America. [1] This is due to Tennessee's limestone rich geology, the primary mineral required to form caves. [2] [3]
Basalt columns seen on Porto Santo Island, Portugal. Columnar jointing of volcanic rocks exists in many places on Earth. Perhaps the most famous basalt lava flow in the world is the Giant's Causeway in Northern Ireland, in which the vertical joints form polygonal columns and give the impression of having been artificially constructed.
[4] [55] In 1957, H. Williams produced a reconnaissance geological map, [4] which was followed by further mapping by E. M. Taylor in 1965. Taylor's work determined the presence of 9 lava units at Sand Mountain Volcanic Field and another lava unit from Belknap Crater. [4] [56] A map published by Sherrod et al. (2004) built upon Taylor's studies. [4]
Tennessee has 59 designated state parks, operated by the Tennessee Department of Environment and Conservation (TDEC). The largest park, Justin P. Wilson Cumberland Trail, is made up of land along the Cumberland Trail, stretching from Cumberland Gap at the Virginia state line to Prentice Cooper State Forest in Marion County, just northwest of Chattanooga.

A lava tube, or pyroduct, [1] is a natural conduit formed by flowing lava from a volcanic vent that moves beneath the hardened surface of a lava flow. If lava in the tube empties, it will leave a cave .
View of Semeru and Bromo eruption with Mount Batok in East Java. The Indonesian island of Java is almost entirely of volcanic origin, and contains numerous volcanoes, 45 of which are considered active volcanoes. As is the case for many other Indonesian islands, volcanoes have played a vital role in the geological and human history of Java.
It rises approximately 2500 vertical feet (762 m) above the lava plain in southern Butte County, east of Craters of the Moon National Monument. Big Southern Butte consists of two coalesced lava domes with a base diameter of 6.5 kilometres (4.0 mi) and a combined volume of approximately 8 cubic kilometres (1.9 cu mi).
The two main types of lava field structures are defined as sheet flow lava and pillow lava. Sheet flow lava appears like a wrinkled or folded sheet, while pillow lava is bulbous, and often looks like a pile of pillows atop one another. [3] An important aspect of lava flow morphology is a phenomenon known as lava flow inflation.
