This is the mouth of the deadly sink hole that swallowed a man as he slept at his home in Florida.
This video was shot when the incident happened in February but has only just been released by Hillsborough County officials.
Thirty-six-year-old Jeff Bush vanished into the hole, 18 metres deep, when it opened up beneath his bedroom.
His brother leapt into the hole, digging furiously trying to find him.
Experts brought in listening devices and cameras in the hope of detecting any signs of life.
Bush's body has never been found amid the clay and debris.
He's now presumed dead.
