Scuba Cemetery

Eternal Reefs and other companies like Great Burial Reef  and Living Reef Memorial offer underwater memorials for the deceased.  Reef balls or other concrete structures hold remains of family members or a community. The cremated remains mixed with concrete to create a reef ball weigh more than 50 pounds and sit underwater in a hive shape structure that can weight up to 4,000 pounds.  It's not going to get lost at sea.
