A channel that is 15' wide.

Most tombs have a stone that is rolled across the entrance to seal the tomb. However, the tomb in this garden has no stone, but there is still there to this day clearly a channel that is 15' wide, that still has the marks of a rolling stone that had once been rolled down the channel to the tomb, which proves that there was once a stone there, as the channel also has a stopper at the end to stop the stone from rolling away after sealing the tomb.
