Solution Cave

solution cave

 

Solution caves are by far the most numerous and extensive type of caves found. The Flint Ridge- Mammoth Cave System of Kentucky is presently over 400 miles in length and is constantly expanding as exploration continues. Solution caves also contain the largest underground chambers. The Big Room of Carlsbad Caverns in New Mexico, for example, is over 300 feet high, 600 feet wide, and 4000 feet long. Most cave diving takes place in caves of this type.

Lava-Tube Caves

Lava tube cave

 

Lava is molten rock that has been extruded from a volcano onto the surface of the earth. On an informal basis, the rock formed by the cooling and solidification of the lava is also commonly called lava, although it can be given a formal geologic name based on its mineral composition.

Sea Caves

sea cave

 

Sea caves are formed by the hydraulic battering-ram effect of waves crashing against cliffs. There is a common misconception that sea caves form in beds of soft rock that occur at sea level and are overlain by harder rocks. However, the examination of numerous sea caves has revealed that vertical planes of weakness, such as faults, promote the development of sea caves regardless of the rock type. Many sea caves have spectacularly large entrances and some, like Sea Lion Cave in Oregon or Anemone Cave in Maine, have enormous rooms. However, passage development in sea caves is usually not extensive. Sea caves rarely exceed several hundred feet in length because the force of the waves is dissipated rapidly against the walls of the cave.

Coral Caves

Coral cave

Coral is famous for its ability to secrete calcium carbonate and build large limestone reefs. Most living reefs occur in tropical oceans and support extremely diverse communities of marine organisms. Mounds or ridges of coral may grow outward slowly and bridge across intervening open areas. Coral caves are created when the tops of neighboring coral heads grow together to create tunnels within the reef. The passages tendto be small, short, and irre­gular. Projecting coral heads may snag a diver and backing out of a small cave is often very difficult.

Diving Reels And Lines

diving reels

 

In order to safely deploy, retrieve, and control the line during the dive, it must be stored on a reel expressly designed for this purpose.

Cave Dive Lights

dive lights

It is an axiom among dry cavers as well as cave divers that you should always have at least three reliable sources of light. For cavern diving these three sources of light are two underwater lights and the light from the cavern entrance.

Cave Diving Hazards

Cave Diving Hazards

The obvious hazards of water, ceiling, and darkness are found in all underwater caves and are generally anticipated even by those cavern diving for the first time.

Securing The Diving Line

diving line

  A safety diving line carried on a suitable lightweight line reel is, perhaps, the cavern diver's most essential piece of safety equipment. Even the brightest light cannot get a diver, lost in a maze of passages with visibility obliterated by stirred-up sediment, out of a cavern. A safety diving line can. The need for a safety line to insure a fail-safe route to the exit may seem obvious; however, accidents caused by the failure to use a safety line are the most common direct cause of underwater cave fatalities.

Propulsion Technique: Frog kick, Ceiling Pushoff

shuffle kick

 

    The frog kick is useful for generating a great deal of power and thrust for entering high-flow springs (if hand holds are not available), and for moving through large cavern passages quickly. Because the frog kick requires the use of different muscles than either the modified flutter or shuffle kicks, switching over to it occasionally will prevent you from tiring as easily and your legs will be less likely to cramp.

Propulsion Technique: Flutter Kick, Shuffle Kick.

flutter kick

Many different techniques have been developed to enable a diver to move through a cavern without silting. Sheck Exley, one of the world's most experienced cave divers, once described 37 different techniques for moving through an underwater cave. However, if you carefully analyze these techniques, you will find that they use similar approaches to solving the common problem of silting.
