Wednesday, Dec. 30, will be a big day at Ruby Falls.

That’s Discovery Day, celebrating 87 years since the underground waterfall was discovered.

The year was 1928 when Leo Lambert and a team of excavators came across the breathtaking waterfall 1,120 feet below the surface of Lookout Mountain. Lambert named the falls after his wife, Ruby, and opened the area as a public attraction in 1930.

On Wednesday, every visitor will receive a vintage-style postcard and a flyer with fun facts about the cave as souvenirs. The first 87 guests can take the tour for the original $2 entrance fee (now normally $10.95 to $18.95).

Ruby Falls is at 1720 S. Scenic Highway. For more information, call 423-821-2544 or visit www.rubyfalls.com.
