Basil Minns Blue Hole crosses beneath Great Exuma Island from northeast to southwest. The cave is entered through a karst window consisting of a large lake with two openings into the cave. A 10-12 m wide passage extends for several hundred meters at 50 m depth, before opening into a 50 m wide, well decorated room. This circular room contains a breakdown mound in the center with an air dome above, but no apparent opening to the surface.
