Blue Hole (Castalia)
The Blue Hole is a fresh water pond located in Castalia, Erie County, Ohio, in the United States. From the 1920s to 1990 the Blue Hole was a tourist site, attracting 165,000 visitors annually at the height of its popularity, partly because of its location on State Route 269, about southwest of the Cedar Point amusement park in Sandusky, Ohio.
Mel's Hole
Waters made guest appearances on Bell's show in 1997, 2000, and 2002. Rebroadcasts of those appearances have helped create what's been described as a "modern, rural myth". The exact location of the hole was unspecified, yet several people claimed to have seen it, such as Gerald R. Osborne, who used the ceremonial name Red Elk, who described himself as an "intertribal medicine man...half-breed Native American / white", and who told reporters in 2012 he visited the hole many times since 1961 and claimed the US government maintained a top secret base there where "alien activity" occurs. But in 2002, Osborne was unable to find the hole on an expedition of 30 people he was leading.
