Snottite, also snoticle, is a microbial mat of single-celled extremophilic bacteria which hang from the walls and ceilings of caves and are similar to small stalactites, but have the consistency of nasal mucus. The term "snottite" was given to these cave features by Jim Pisarowicz in Stalagnate results when stalactites and stalagmites meet or when stalactites reach the floor of the cave.
Sea cave, cave formed in a cliff by wave action of an ocean or lake. Sea caves occur on almost every cliffed headland or coast where the waves break directly on a rock cliff and are formed by mechanical erosion rather than the chemical solution process that is responsible for the majority of inland caves.
Typically made of calcite, gypsum or aragonite, cave popcorn is named after its distinctive shape. Boze says many different geologic mechanisms can create cave popcorn. The longest free-hanging stalactite in the world is 28 m 92 ft long in the Gruta do Janelao, in Minas Gerais, Brazil. Living things usually grow during their life cycle.
Note that the word "grow" refers also to non-living things which can get larger. Examples are crystals, stalactites, and stalagmites. Many living things move on their own although some, like plants, do not. All limestone stalactites begin with a single mineral-laden drop of water. When the drop falls, it deposits the thinnest ring of calcite.
Each subsequent drop that forms and falls deposits another calcite ring. Two of the most common and popular types of speleothems are stalactites and stalagmites. Stalactites grow downward from cave ceilings. They begin to form as straws but eventually grow into stalactites as the straw form becomes blocked with calcite. If they grow big enough , stalactites and stalagmites meet and join. But as they grow very slowly it takes hundreds of thousands of years.
After they met they are called a pillar or column. There are numerous shapes of such pillars, as there are numerous shapes of stalactites and stalagmites. It is most commonly seen as delicate white crystal found along tour routes such as Cleveland Avenue and Kentucky Avenue.
Along Broadway in historic section of Mammoth Cave you can also see gypsum, but it is covered with a dark coating so it looks dark brown instead of white.
The coating on this gypsum is from smoke from the torches that people used in the cave — years ago. Gypsum will also grow as crystals in the dirt along some cave passages. Crusts — Crusts are where gypsum lines the walls as thin or sometimes thick plate covering actually extruding from the limestone. Flowers — Gypsum may also grow outwards in shapes that resemble flowers.
This occurs in areas such as Cleveland Avenue and Kentucky Avenue. Flowers, like crusts, form as the gypsum extrudes from the rock like toothpaste from a tube. In a crust all the crystal grow at about the same speed, but to form a flower, some of the crystals grow faster than others.
Snowballs —This formation is the one that gives the Snowball Room its name. They are globular white gypsum balls that cover the ceiling. Mirabilite and Epsomite are two other minerals that occur in dry sections of the cave.
They can form in areas in the winter when the air is drier and dissolve away when more humid air comes in. They form a sprinkling on the floor that gives the Snow Room on the Lantern Tour its name. Towering passageways, mountainous heaps of fallen rock, and a maze-like sprawl.

Stalactites, Stalagmites, and Cave Formations. These broken cave formations, near the Frozen Niagara section of Mammoth Cave, may take centuries to regrow.
Studying underwater caves, such as those in Bermuda , can give us clues about how climate and sea level have changed over time. This knowledge can, in turn, help us better understand and respond to current climate and sea level fluctuations. What is a Karst?
