Outdoor burial system for urns

A non-mechanical outdoor urn burial system that includes a one-piece rigid weather resistant tubular vault directly embedded within an outdoor ground surface with a length of the vault extending perpendicular to the outdoor ground surface, the vault having an open top, a closed end, and an elongated chamber having a dimension configured to support one set of urns completely below the ground surface in a stacked condition wherein access to the chamber is through the open top, a weather resistant cover disposed to close the open top and seal the chamber from environmental conditions, and at least two urns each having a top end and a bottom end and disposed top end-to-bottom end in a stacking yet independently displaceable condition in the chamber with each urn including a slot located proximal the top end to facilitate the independent transfer of the urn within and out from the vault.
