DescriptionKohtla mine.jpg | Small <a href="http://en.wikipedia.org/wiki/Stalactite" rel="nofollow">stalactites</a> formed under the concrete clad ceiling of a mining shaft in the Kohtla mine in Estonia. Such stalactites are formed the same way as in natural caves, when mineral rich water drips from the ceiling. Over time some of the mineral sticks to small bumps in the ceiling and slowly grows downward, like icicles, to form long, sharp stalactites. | ||
