The Caverns of Sonora is a National Natural Landmark due in part to the phenomenal display of speleothems known as "helictites" and in particular "bladed helictites," rare and beautiful cave formations. DANGLING DEPOSITS Cave formations come in numerous shapes and sizes, and many of their names--popcorn, cave bacon, and soda straw, for example--seem to have sprung from the minds of imaginative--and hungry--cavers. Calcite, or calcium carbonate, is the main constituent of limestone and of cave formations such as stalagmites and stalactites. |
