CAVE CITY, Ky., Dec. 1 - Subterranean explorers announced today their discovery of a long-sought link between two of the world's major cave systems, which stretch for 150 miles underground.

The discovery was made three months ago by a party of five men and a woman that spent 16 hours, often in water up to their necks, worming seven miles underground to locate the long-suspected connection between the Mammoth Cave and the Flint Ridge Cave systems.

"It was like going through a huge bowl of spaghetti - except that we went through the tubes in the strands," said the party's leader, Dr. John P. Wilcox of Columbus, Ohio

More cave stuff. Looks like Cleveland, Ohio is ripe with caves and tunnels, too.

Note the date on that article - 1972. As of last year, the length of the Mammoth Cave complex has exceeded 300 miles!
