Worth looking at for learning about Caves, Limestones and Karst environments.
Karst
“Is the name for the geological structures that turn a land into a sieve. Where water rushes through thin soil and porous bedrock to seep into deep and hidden caverns and channels below.
Imagine swiss cheese or an elaborate labyrinth created by chemistry, physics and water as it restlessly seeks the path of least resistance over eons.
That water is essentially invisible to those above, bypassing the land and their needs.
Karst would have been a good name for a dragon. With its harsh and mighty sound.”

Cave entrances —-Caves and cracks in karst ——–Sinkholes
Waitomo Karst is Unique in that we have POLYGONAL Karst features. A large amount of sinkholes (dolines) are connected together to form a honeycombed or egg carton depressions on the landscape. On a world scale we have many closely spaced sinkholes within some areas of Waitomo.
Other features of highlight are the mudstone caps and ignimbrite (volcanic) caps over the limestone creating differences in karst around Waitomo.

Limestone to Caves
Limestone is the most common material that caves are found in. (Limestone chemically dissolves and wears easily over time, creating larger channels within the rock, leading to cave passages and chambers). Waitomo Limestone is between 28- 22 mya and is very compacted and crystaline. Very “pure” meaning having a large component of Calcium Carbonate present.
New Zealand’s largest caves are Nettlebed or Bulmer, or Gardners Gut in the North Island. http://caves.org.nz/pmwiki/pmwiki.php/NZSS/LongestCaves
On the world stage we have some impressive cave systems. (A geologically young country). http://www.caverbob.com/wdeep.htm
