Weekly Photo Challenge: Time ( Stalactite and Stalagmite )

We only perceive time through changes.

However, both stalactite and stalagmite in caverns only grow very slowly.DSC_0198

Limestone stalactites in particular form extremely slowly – usually less than 10 cm every thousand years – and radiometric dating has shown that some are over 190,000 years old.

Here are a couple of photos taken in the limestone caverns of Yunnan, China.DSCF2894A

While I am in awe with these formations, I don’t particularly fancy seeing them lit up in multi-colors.

I prefer seeing them in their natural color and state.
