Poole’s Cavern is the most spectacular natural cavern in the Peak District, England. The cavern is famous for the spectacular and unique crystal formations. A stalagmite is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites are typically composed of calcium carbonate, but may consist of lava, mud, peat, pitch, sand, sinter, and amberat.
