Tennessee's Lost Sea recognized as largest underground lake in America

The Tennessee Agriculture & Natural Resources Committee meeting on February 11, 2025, kicked off with a captivating presentation on the state's unique geological treasure, the Lost Sea. This underground lake, discovered in 1905 by a young explorer, is recognized as America's largest underground lake and the second largest in the world. Stretching 800 feet long and 220 feet wide, the Lost Sea has intrigued researchers and adventurers alike, with divers uncovering over 13 acres of water and a series of expansive underwater rooms.

The meeting highlighted the historical significance of the caverns, which have served various purposes over the years—from Cherokee housing to Civil War saltpeter mining. Notably, a soldier's inscription from 1863 was found within the caverns, adding to its rich narrative. Today, the Lost Sea is a registered national landmark, attracting visitors for glass-bottom boat rides, although fishing is prohibited to protect its thriving population of rainbow trout.

Following the discussion on the Lost Sea, the committee shifted focus to a presentation by Gary Cohen, the volunteer outreach director for the Tennessee Waste to Jobs Coalition. Cohen, along with representatives from Kaiser Aluminum and Florum USA, addressed the pressing issue of solid waste management in Tennessee, emphasizing the economic opportunities that could arise from innovative waste solutions.

As the committee continues to explore these vital topics, the significance of Tennessee's natural resources and the potential for sustainable economic growth remain at the forefront of their agenda.
