Summary
[edit]DescriptionHelictites and Stalactites Growing out of the Rim of a Broken Stalactite.jpg | A stalactite was broken by unscrupulous visitor some time between its discovery by Lehman in 1881 and its eventual protection by the National Park Service sometime around 1950s. Within about 50 to 100 years, new tiny stalactites and helictites grow along the rim of the broken stalactite. This photo vividly shows the resilience of nature and the extreme slow speed a stalactite grows. |
