Blue Hole (Castalia)
The Blue Hole captured the public’s interest because of its size, about in diameter, clarity, vibrant blue hue, and enigmatic "bottomless" appearance. Contrary to prevalent belief, the depth of the Blue Hole is not unknown, but has been sounded and found to be about deep. Water temperature is about throughout the year. Floods and droughts have no effect on temperature or water level. The Blue Hole is fed by a passing underground stream which discharges of water daily into Sandusky Bay to the north, feeding into Lake Erie. The water contains lime, soda, magnesia and iron, and because the Blue Hole is anoxic, it cannot naturally sustain fish. The surrounding terrain is developed on limestone bedrock and exhibits karst topography due to dissolution of the limestone by ground water, creating water-filled sinkholes. The Blue Hole was known to American Indians and was first recorded in history in 1761. Several similar blue holes are known to local residents. The Blue Hole that once was a tourist attraction is now off limits to the public. It is located on the grounds of Castalia Trout Club. It is to be distinguished from another hole similar in size and eerie bluish-green color. This latter hole is owned by the Castalia State Fish Hatchery operated by the Ohio Department of Natural Resources, Division of Wildlife and is open for public viewing.
Temescal Canyon High School (Lake Elsinore, California)
The "Blue Hole", a school-wide pep club, forms a large part of Temescal Canyon student culture. Formed in 2002 by members of the football team who wanted something to do during the offseason, the Club is now an official school club open to all students. Members purchased TC-Blue T-shirts with a "6" on the back (symbolizing the 6th man) and "Blue Hole" in large, bold lettering on the front. They appear at basketball games, home and away, and sit behind the opposing team's bench. From beginning to end, they stand and chant phrases, hoping to mentally defeat the opponents as well as motivate their fellow student-athletes. Their antics include repeatedly heckling individual players with chants of "air ball", the turn-over countdown, and other attacks on play or attitude. The antics even target the officials, as poor calls are followed by boos and members dress as blind referees and parade the sidelines after a questionable call. The Southwestern League prompted new regulations prohibiting the club from sitting behind the opposition bench and name calling. The Club's rowdiness has been credited to some of the success of the boys' basketball team. The Blue Hole has also moved onto the football field, where they sit in a specially-marked "blue hole section", a seating area in which the bleachers are painted blue. Standing throughout the entire game, the Blue Hole cheers and sings, capping it all off with an "It's All Over" chant at the end of a victory.
