69-year-old Mary Agnes Vodde-Hamilton's Facebook post revealed her desire for a coral reef memorial using Eternal Reefs' service.

69-year-old Mary Agnes Vodde-Hamilton's last Facebook post led her children to discover her desire for a coral reef memorial. Florida-based charity, Eternal Reefs, partners with families to incorporate cremated remains into structures called reef balls, which are then placed on the ocean floor to support coral reef growth and underwater sea life while creating a living, underwater memorial.
