Went to the Lost Sea this past Friday. The guide "claims" there is a room below or adjacent to the underground lake that divers attempted to explore in the past (he didn't know a date or what type of divers) and were unable to do so for a couple reasons.... A) and I quote "they ran out of rope"; and B) again I quote "their breathing bubbles were causing a cave-in".

Just out of curiosity, does anybody know about this attempt? Have any local cavers in the TN area tried to gain access recently?

This is obviously a commercial cave that is privately owned. They've put trout in the underground lake, so if there were any normal cave critters, they are long gone now.
