Dominating Giant’s Hall at a height of 47 feet, this column is the tallest and one of the most spectacular formations in the caverns. The Double Column is a classic example of the two basic cave formations the stalactite and stalagmite. Luray Caverns is noted for the profuse variety of formations and unsurpassed natural color. All coloration in the caverns is natural, caused by the mineral content of the seeping ground water. The ceiling here in Giant's Hall is over 60 feet in height. From the standpoint of total airspace, this is also the largest room in the caverns.
