Abstract: A portable burial system for interment of cremated remains of humans and/or pets that provides for complete underground burial in keeping with traditional burial practices is disclosed. The present burial system includes an ornamental marker structure, which is attached to an underlying supporting plate mounted on the ground surface. The supporting plate is also attached to an underlying burial container assembly and supports the container assembly with the interred cremated remains in a completely buried condition. The container assembly includes a tamperproof closure to provide a permanent seal and to prevent unauthorized access to the cremated remains. All of the burial system components are constructed of materials capable of resisting corrosion for an appreciable period of time under the intended conditions of use.
