CAVE STREAM: The name says it all.Situated amongst the Karst topography (limestone outcrop) in Canterbury, NZ, is a 594m long underground cave which, you guessed it, has a stream flowing through it.The cave was formed slowly, with slightly acidic water dissolving the limestone over time. Where the stream once flowed is still very clear, leaving a small dry valley upstream (you can almost see the valley in the bottom right of the 2nd image). You can go through the cave - just remember a bright torch and a warm wetsuit (and be careful of the eels!) In the second photo you can see the exit of the cave.The cave is home to the Cave Harvestman, a spider that is known to live only in that cave and one other on the West Coast.-MJAReference/Further Reading: http://bit.ly/1Fu0UdwImage credits: Marcus Arnold. -- source link
