This dive site, known as Belcher Mine, also referred to as The Jewel or Jewel Sink, is a former limestone quarry located in the Sunwest Mine in Florida, USA. Operational in the 1980s, mining activities breached the ceiling of a vast natural cavern. While its shallower sections were historically utilized for Open Water Diver checkout dives, the site's significant feature is a cavern at 14 meters (45 ft) that extends into complex cave systems and rooms reaching depths exceeding 91 meters (300 ft), demanding specialized training for exploration. It is currently closed to all diving activities.
Given its origin as an inland limestone quarry, specific marine animals and plants are not typically associated with Belcher Mine. The description does not mention any aquatic life, and the 'backish water' suggests potentially limited or freshwater species, but no details are provided about its ecosystem.
The primary 'highlight' and critical information for Belcher Mine is that it is CURRENTLY CLOSED TO DIVERS, rendering any travel planning or diving tips moot. If it were open, the extensive cave system would be its main draw for experienced technical divers, contrasting with the shallower, poor visibility areas previously used by beginners.
