Delicate, string-like formation stretches from one stone to another
Photo by Steven M. Bumgardner
These gravity-defying cave formations are known as helictites. They form due to the capillary action of acidic solutions and are composed of the minerals calcite and aragonite. These formations are small, with the longest helictite being about 8 inches in length. These grew in the Betelgeuse Balcony area of Hurricane Crawl Cave.

Lilly pad formation in the Pumpkin Palace of Hurricane Crawl Cave

Vivian Loftin appreciates a beautiful, crystalline "lily pad" formation. These develop near the top of pools of water when crystals of calcite grow across the surface tension of very still pools. These formations are in a corner of the largest room in Hurricane Crawl Cave, Pumpkin Palace.

A caver in Pumpkin Palace in Hurricane Crawl Cave. This is the largest room in the cave and is more than 90 feet in diameter. Notice that the caver is not wearing boots and has on a clean caving suit. Cave explorers work very hard and are very careful to protect such delicate formations.

Delicate stalactites and soda straw formations in Crystal Cave. The drops of water on the ends of the formations mean that they are still actively growing.

Tourists enjoy the views in Marble Hall, the largest room in Crystal Cave. Crystal Cave was developed for public tours in 1938 and 1939 and has since had well over 1 million visitors.
 
Cave pearls lie in a cave pool

Cave pearls in Crystal Cave. These form when acidic water deposits rock on grains of sand or small rocks. The dripping water keeps the developing formations moving and so cave pearls remain unattached to the cave floor.
 
Spar crystals in the Aragon Room of Soldiers Cave

Beautiful spar crystals in the Aragon Room of Soldiers Cave. These crystals, which are several inches long, formed under water.

A thundering waterfall deep inside Lilburn Cave. Notice the banded marble bedrock and the caver's protective clothing.

A March 1950 photograph of the columns at Column Pit in Soldiers Cave. This section of the cave had only recently been discovered at this time. For many years to avoid the pit in the floor (which can't be seen in this picture) cavers traveled between the white columns and the white wall.

In response to the damage to the cave the National Park Service sponsored an extensive clean-up and restoration of Soldiers Cave between 1993 and 1995. Many California cavers volunteered their time and equipment for the project. The work involved hose washing some areas of the cave including Column Pit.

Today the formations at Column Pit are protected by a ladder that cavers now use to cross the pit. Red flagging tape reminds cavers not to touch the columns and other formations the area.
