Calcium carbonate latter is especially evident in day-to-day life of people who have hard water. Water in aquifers underground can be exposed to levels of CO much higher than atmospheric. As such water percolates through calcium carbonate rock, the CaCO dissolves according to the second trend. When that same water then emerges from the tap, in time it comes into equilibrium with CO levels in the air by outgassing its excess CO. The calcium carbonate becomes less soluble as a result and the excess precipitates as lime scale. This same process is responsible for the formation of stalactites and stalagmites in limestone
Cave of the Winds (Colorado) Cave Coral, or Cave Flowers; also commonly considered to be Beaded Helectites which appear to defy the laws of gravity by growing in strange directions and not being forced down by gravity like many cave formations. Silent Splendor is sealed from public view by an Environmental Gate, a large tube made of PVC that seals in moisture to allow the area of the cave to continue forming. Other lesser known attractions include a "bottomless pit," often the scene of practical jokes by the guides, and a one of a kind region referred to as "the rat." In the late 1980s
