Caving in Devon- Helictites and other formations...

 
   
       
 

Caving in Devon- Helictites (pictured on the right) can be found on the walls and ceilings of caves, they can also be found growing from stalactites and straws. The formation of helictites is still not proven, they seem to defy the laws of gravity and grow out sideways from the wall...

Stalactites, stalagmites and other speleothems are formed by calcium carbonate and other minerals dissolving the limestone and depositing themselves on the rock. The average growth rate for a stalactite is 0.13mm a year...imagine how long it takes to form the large features we see in caves today!

Caving Conservation- caves are home to delicate and often stunning formations, it is very important for us to respect this environment and leave everything as we find it...this includes not touching any of the features, one fingerprint can stop the growth of a formation which could have taken hundreds of years to reach its current state.
