caused by lateral outgrowths of crystals growing from the side of an active stalactite, or to deflections caused by currents of air, or to the existence of a diminutive fungus peculiar to the locality and designated from its habitat Mucor stalactitis. The dimensions of the chambers included in Luray Caverns cannot be easily stated, due to the great irregularity of their outlines. There are several tiers of galleries, and the vertical depth from the highest to the lowest is . Luray Cavern waters There is a spring of water called Dream Lake that has an almost mirror-like appearance. Stalactites are reflected in the water making them appear to be stalagmites. This illusion is often so convincing that people are unable to see the real bottom. It looks quite deep, as the stalactites are higher above the water, but at its deepest point the water is only around deep. The lake is connected to a spring that continues deeper into the caverns. The Wishing Well is a green pond with coins, deep at the bottom. Like Dream Lake, the well also gives an illusion, however it is reversed. The pond looks deep but at its deepest point it is actually deep. See also List of National Natural Landmarks in Virginia References Further reading Ryder, J.A.
