Caves in the interior ridges (ruku) of the islands formed through the dissolution of the bed-
rock usually beginning along fault lines in the rock where acidic rainwater easily dissolves
the limestone.

These caves typically have two components. Vertical sections created by the downward
flow of rainwater, and horizontal sections created by the flow of underground streams.
The highest rate of dissolution occurs on the margins where underlying salt water mixes
with the overlying freshwater lens creating what geologists call "flank margin caves." In
these caves, rounded tunnels are spaces that once were completely filled with water,
while triangular and rectangular tunnels result from streams running across the floor.

Caverns are large openings where several tunnels meet. They often have very high ceilings
with substantial amounts of collapsed rock from the roof lying on the floor and multiple
openings in the ceiling. Lakes (xara) can occur where the depth of the cave reaches the
water table. The longest explored underwater cave system in the Bahamas is Lucayan
Cavern on Grand Bahama Island with passages extending for more than five miles.
