Coast to Coast AM with Art Bell on February 21, 1997. Mel Waters was on talking about a weird opening on his land near Ellensburg, Washington. The land had been in the family for generations passed on from his dad to Mel. The locals had been using the hole as a convenient garbage dump for decades. One man had dropped his dead dog into the hole to dispose of the body. Later that week he saw his dog running around his property. People began to believe the hole had some kind of paranormal abilities.
Waters said he owned rural property nine miles west of Ellensburg in Kittitas County, Washington that contained a mysterious hole. According to Bell's interviews with Waters, the hole had infinite depth and the ability to restore dead animals to life. Waters claimed to have measured the hole's depth to be more than 80,000 feet by using fishing line and a weight. According to Waters, the hole's magical properties prompted US "federal agents" to seize the land and fund his relocation to Australia.
Here is what I could find about this hole and what has become of Mel Waters.
