Deep inside a mountain near Sweetwater in East. Tennessee is a body of water known as the Lost Sea. It is listed

by the Guinness Book of Would Records as the world’s largest underground lake. The Lost Sea is part of an

extensive and historic cave system called Craighead Caverns.

The caverns have been known and used since the days of the Cherokee Indian nation. The cave expands into

a series of huge rooms from a small opening on the side of the mountain. Approximately one mile from the

entrance, in a room called “The Council Room,” many Indian artisfacts have been found. Some of the items

discovered include pottery, arrowheads, weapons, and jewelry.

For many years there were persistent rumors of a large underground lake somewhere in a cave, but it was not

discovered until 1905. In that year, a thirteen-year-old boy named Ben Sands crawled through a small opening

three hundred feet underground. He found himself

in a large cave half filled with water.

Today tourists visit the Lost Sea and ride far out onto it in glass-bottomed boats powered by electric motors.

More than thirteen acres of water have been mapped out so far

and still no end to the lake has been found. Even though teams of divers have tried to explore the Lost Sea,

the full extent of it is still unknown.

A. part of a historical cave system

B. the biggest underground lake in the world
