This stunning image is of “Crystal Cave” in Yanchep National Park, Western Australia. The Limestone cave has been formed by an underground stream which flowed Westwards from Gnangara Mound. The cave is small as the water table is only around 10m from the surface, and Crystal Cave has no permanent water source due to drought conditions in WA (the water table has been falling over the last few years, and intervention to pump water into the cave was unsuccessful as it began to effect the above ground water supply and the associated flora and fauna) The cave contains every type of Speleotherm imaginable; Stalactites, stalagmites, shawls, straws, flow-stone and bacon (where iron minerals from the ground water give the Speleotherm a pinkish tinge and makes it look like a rasher of bacon). Crystal Cave is only one of several hundred in the park, and a few are accessible to the public for tours or for caving activities.
