Four Shark Cave is an offshore ocean blue hole located inside the barrier reef, along the fault line 5 km northwest of Dolly Cays, South Andros. The entrance is a coral rimmed basin about 10 m deep that opens into one of the largest caverns in the Bahamas. This 70 m long, 20 m wide chamber known as the Kalik Cavern extends to 60 m depth. At the far end of the cavern, a narrow crack at 40 m depth descends into a continuation of the fissure with depths from 50 to 105 m or greater. In the entrance zone, the bottom consists of sand and fine white silt. Strong tidal currents exchange reef water with that from the interior of the cave.
